voltage, amperage and resistance definition formula abbreviation units
Voltage: The force or pressure that pushes electrical current through a circuit. In an equation, voltage is represented by the symbol V and is measured in Volts (V).
Amperage: The amount of electrical current flowing through a circuit. In an equation, amperage is represented by the symbol I and is measured in Amperes (A).
Resistance: The opposition to the flow of electrical current in a circuit. In an equation, resistance is represented by the symbol R and is measured in Ohms (Ω).
Ohm's Law: The relationship between voltage, amperage and resistance is given by the formula V = I x R, where V is the voltage, I is the amperage, and R is the resistance.
