Simulation Based

The experiment of determining the value of the Planck constant using Simulation Based Laboratory is done in order to compare the value of the Planck constant in theory to the value of the Planck constant through experimentation. This experiment wpas done using PhET simulations. Photoelectric effect is an event where when a beam or photon is worn on a substance, it will release the electron and the electric current. In the equation of photoelectric effect, the most important is a constant, the Planck constant. The result of the experiment obtained the Planck constant value is J. s with a relative error of 0.15%, while based on the theory of the value of the constant Planckis J. S can be concluded that the results of the experiment carried out close to the theory.

Length Effects

Chemical sources of current are investigated as lines with distributed parameters. Analytical expressions are obtained for the voltage and active power values of the source at different distances from the beginning of the cell as well as dependences of the working voltage and active power on the source length. Effects of a reduction in the operating voltage and active power are due to the flow of electric current along the source during operation. The magnitude of these effects depends not only on the length of the source, but also on the ratio of characteristic resistance to the load resistance.<br>
