Triangle Electric Current Formula

The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω.

Triangle electric current formula. The power p in watts w is equal to the voltage v in volts v times the current i in amps a. Generally electrical power is dissipated in the form of heat heaters mechanical work such as motors energy in the form of radiated lamps or as stored energy batteries. Electric power calculator calculation general basic electrical formulas mathematical voltage electrical equation formula for power calculating energy work power watts calculator equation power law current charge resistance converter ohm s law and power law power formulae formulas understandimg general electrical pie chart two different equations to calculate power electricas ohms law audio. As electrical power is the product of v i the power dissipated in a circuit is the same whether the circuit contains high voltage and low current or low voltage and high current flow.

As the power triangle relationships of this simple example demonstrates at 0 5263 or 52 63 power factor the coil requires 150 va of power to produce 79 watts of useful work. In other words at 52 63 power factor the coil takes about 89 more current to do the same work which is a lot of wasted current.
