Ohm''s law (V = IR) measures the voltage across the load. The generator''s design, which includes the rotor (the rotating element) and the stator (the stationary part), is crucial to defining the system''s

In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
