= Electronics = Both digital and analog components == Properties == _Voltage_ is the electrical potential. It is similar to water pressure in a pipe. Voltage is polarized, and relative, therefore it is often measured with respect to the earth, or _ground_. A parallel circut always has the same voltage across all components. _Current_ is the flow of electricity. It is similar to water flow in a pipe. Current is not polarized, and not relative. A series circut always has the same current across all components. These two are related via the following equation (Ohms law): V = I * R Where V is voltage (Volts), I is current(Amps), and R is resistance(Ohms). Power is Voltage times Current and is measured in Watts (W). Power is a rate upon which electrical energy is used.
