Power


Voltage


Amperage


Ohm

Detailed explanation1: Ohm’s law can be expressed in three ways: If the resistance and current are given, but the voltage is unknown, Ohm’s law can be written as voltage is equal to current multiplied by resistance. It is expressed mathematically as V=IR V = I R .
Detailed explanation2: Ohm’s Law shows the relationship between the three quantities: voltage, current and resistance. Ohm’s Law can be written as a word equation: voltage = current × resistance. Or using symbols to represent the quantities of voltage (V), current (I) and resistance (R): V = I × R.
Detailed explanation3: When spelled out, it means voltage = current x resistance, or volts = amps x ohms, or V = A x .
Detailed explanation4: where I is the current through the conductor, V is the voltage measured across the conductor and R is the resistance of the conductor. More specifically, Ohm’s law states that the R in this relation is constant, independent of the current.
