Voltages are produced by converting one form of energy into electrical energy. Mechanical energy can be converted into electrical energy (voltage and current) by moving a magnet or magnetic coil in proximity with a stationary coil, connected to an electrical circuit. A voltage can also be produced with a chemical reaction. Batteries and fuel cells convert energy in specially designed cells, where a chemical reaction causes a voltage to exist across two electrodes implanted at two different parts of the cell. A voltage can be produced by the interaction of light on a photocell. The photons of light interacting with atoms in the photocell, cause an electron to be ejected. The special design of the photocell causes this to occur in such a manner as to produce voltage across the cell. A voltage can be produced by subjecting a thermocouple to differential temperature. A thermocouple is a relatively simple device composed of two dissimilar metals, joined together at what is referred to as a thermal junction.
