E = I * R or Volts = Amps * Resistance. One volt of electrical potential equals one amp of current times one ohm of resistance.
The relationship between voltage, current and resistance in a DC circuit. If two values are known the other can be calculated. This relationship is expressed many different ways. The basic relationship is voltage (V) is equal to current (I) multiplied by resistance (R). Ohm's law must be applied in a modified way to AC circuits. AC circuits have impedance rather than resistance. Impedance causes AC circuits to exhibit power factor, which must be factored into any calculations
The mathematical relationship between ohms(R), volts(V) and Amps(I). Technically is states that current (I) is directly proportionate to voltage and inversely proportionate to resistance. The mathematical equations are: V = I x R or I = V/R or R = V/I or
