Electrical circuit components or electronic circuits can be connected with series and parallel circuits. The arrangement of the circuit can affect the desired lamp characteristics. This study aims to measure the magnitude of resistance in an electrical circuit, analyze the flame of a series and parallel resistance, explore the relationship between voltage (V) with current (I) in series and parallel circuits. The method research used quantitative methods based on the problem-solving laboratory. The laboratory equipment used consists of a battery, incandescent lamps, resistors, stacking and zinc puzzles, multimeters, jumper cables. The laboratory equipment assembled and measured the intensity of the light produced using the physics toolbox application on a handphone. The data has obtained, then presented in a table and calculated using a formula, and analyzed the uncertainty in its measurement. The result showed the intensity of light in a series of different magnitude, the power of the light was more significant in lamp one, and in lamp two, the power was smaller. The intensity of the light in the parallel circuit was the same magnitude. Still, the value of the light intensity in the parallel circuit was smaller than the intensity in the lamps arranged in series. The relationship between voltage (V) and current (I) in both series and parallel circuits was comparable and directly proportional. Thus, the developed series of electric puzzles can adequately explain Ohm’s law. Ohm’s law learning with electric puzzles can be used in school and learned by students quickly.

<p class="Abstract">A thermoelectric cooler (TEC ) is a component of an electric solid-state cooler that works as a heat pump in the cooling process. Utilizing the peltier effect that is when an electric current is flowed heat absorption occurs on both sides of the thermoelectric and the release of heat on the other side. The use of thermoelectric as a coolant in cool box systems has been widely studied. The purpose of this study was to determine the performance of the cooler using thermoelectric based on the circuit and air velocity in the wind tunnel. The studied performance includes temperature difference, heat absorption, and coefficient of performance. The method used in this study is a real experimental method, with research variables namely series and parallel thermoelectric series and wind tunnel air velocity. Data were taken in the form of cool room temperature cold side temperature, hot side temperature, heatsink temperature, and ambient temperature. Thermoelectric connectivity electrically uses series and parallel circuits and is thermally arranged in series. The results showed that the thermoelectric circuit and wind tunnel air velocity affect the performance of the thermoelectric. Thermoelectric with series circuit produces the highest COP absorption compared to the parallel circuit. The highest performance thermoelectric series is obtained at an airspeed of 9.8 m/s. in these conditions the temperature difference (AT) produced reaches 19<sup>o</sup>C. the heat absorption (q<sub>c</sub>) reaches 34.26 watts and the COP reaches 0.89</p>

A series circuit is a parallel circuit or a circuit system that connects from a voltage source (V) to a load, while a parallel circuit is a branching circuit that connects from a voltage source to a load. The measurement process in the electric power system is one of the standard procedures that must be carried out, because through the measurement, the required quantities will be obtained in accordance with the requirements of PUIL 2000. three phases by making a series and parallel installation circuit. The method used in this research is to test, measure and calculate the value of voltage (V), current (I), resistance (R) and load power (P) in a series of single-phase and three-phase electrical installations in series and parallel. Based on measurements and calculation results, the maximum total current generated in a single phase series circuit installation is 82.57 Ampere, which applies equally to L1, L2, L3 and L4. The maximum total current generated in a parallel circuit is 129.35 Amperes at L1 and a minimum current of 96.29 Amperes at L4. For the maximum real power (P) generated in a single-phase series series installation is 13872 Watts and in parallel circuits is 21523 Watts, for the maximum apparent power (S) generated in a single-phase series series installation is 17339 Watts and in parallel circuits is 26904 Watt. While the maximum total current generated in a three-phase series series installation is 94.33 Amperes, which applies equally to L1, L2, L3 and L4. The maximum total current generated in a parallel circuit is 150.56 Amperes at L1, and a minimum current of 120.17 Amperes is located at L4. For the maximum real power (P) generated in a three-phase series series installation is 34637 Watt and in a parallel circuit is 54876 Watt, while the maximum apparent power (S) generated in a series circuit is 43297 Watt and in a parallel circuit is 68595 Watt.

The purpose of this description is to analyze the results of student learning physics education in sub subject Ohm's law and Kirchoff laws in subject 1 Basic Electronics and possible solutions, which are expected to minimize the percentage of errors. The author uses quantitative methods to support this description. First of all, I have shared the instruments to students of the third semester. Then from the results obtained, the authors categorize the types of errors, analyze and find the reason of the student errors. Once analyzed, the authors obtain the result that the students' understanding of the application of Ohm's law in category 3, the percentage of the greatest mistakes that 90%, followed by the category 1 by 80% and the lowest category of 2 (20%). Then from the results of the analysis of Kirchoff laws, obtained the largest percentage error in the category of category 3 by 90%, then 40% of category 2 and category 1 by 10%. From the analysis it can be concluded that the ability of students to master the fundamental law of electricity is low.

In an effort to develop the generic skills of science students conducted research to reveal the ability to describe the relationship between the concept of students in learning science / physics topic in class IX Ohm's Law. To know how to profile a student's ability in describing the relationship between the concepts of physics on the topic of Ohm's Law of Free Inquiry-based learning carried out in one class IX SMP Negeri 2 Cikalongwetan. Achieving the ability of students and percentage of students who achieve the ability to describe every aspect of the relationship between concepts is measured by observation and assessment products in the form of journal the results of the experiment. The results of this study indicate that the highest and lowest achieving students to aspects of the writing tables in the indicator unit 59% and 12% of the write indicator; create a chart on the indicator to write on both axes coordinate the writing of 78% and the indicator unit on the second coordinate axis 22%; describe relationships between concepts in the form of sentences in two variables load indicator 100% and the indicator shows the quality of the relationship between variables 35%; and describe the relationships between concepts in the form of symbols on the indicator symbol contains 87% 2 variables and indicators to formulate the relationship between symbols 13%.

This study was aimed to evaluate the Malay proficiency among students in Form Two especially non-Malay students and its relationship to academic achievement History. To achieve the purpose of the study there are two objectives, the first is to look at the difference between mean of Malay Language test influences min of academic achievement of History subject among non-Malay students in Form Two and the second is the relationship between the level of Malay proficiency and their academic achievement for History. This study used quantitative methods, which involved 100 people of Form Two non-Malay students in one of the schools in Klang, Selangor. This study used quantitative data were analyzed using descriptive statistics and statistical inference with IBM SPSS Statistics v22 software. This study found that there was a relationship between the proficiency of Malay language among non-Malay students with achievements in the subject of History. The implications of this study are discussed in this article.
