What are some of the basic 12 volt battery related electrical terms?
Voltage is the pressure of the circuit. Amperes (Amps) is the amount of charge that flows in the circuit per second. Ampere-hours (Ah) measures the capacity of the battery. Load is the electrical device that is drawing power (radio, light, etc). Ohm is the measure of electrical resistance. Direct Current (DC) the electrical current only flows in one direction (opposite of AC or alternating current).
