Power Voltage Resistance Current

This calculator is based on simple ohm s law as we have already shared ohm s law p i v r calculator in which you can also calculate three phase current.

Power voltage resistance current. Power power p is a measure of the rate at which energy is delivered or used by a circuit element. The current is equal to the electromotive force of the source divided by the total circuit resistance. This is called ohm s law. Power voltage current resistance p v i r calculator.

More specifically ohm s law defined that the current i through a conductor between two points is directly proportional to the voltage v and is inversely proportional to the resistance r. R resistance in ohms. It is the most fundamental law that defines the relationship between the current i resistance r voltage v and power p. Using ohm s law we can say.

V voltage in volts. Voltage is measured in volts with one volt being defined as the electrical pressure required to force an electrical current of one ampere through a resistance of one ohm. Voltage sources deliver power while resistors use power by dissipating it as heat. Voltages are generally expressed in volts with prefixes used to denote sub multiples of the voltage such as microvolts μv 10 6 v millivolts mv 10 3 v or kilovolts kv 10 3 v.
