If there is AC, look also at the power factorPF= cosφandφ= power factor angle (phase angle) between voltage and amperage. ElectricEnergyisE=P×t− measured in watt-hours, or also in kWh. 1J = 1N×m = 1W×s Power Formula 2– Mechanical power equation:PowerP=E⁄twhere powerPis...
Amperage I amps Voltage V volts P = I × V I = P / V V = P / I Ohm's law. V = I × R, where V is the potential across a circuit element, I is the current through it, and R is its resistance. This is not a generally applicable definition of resistance. It is only ap...
Explain the relationship between amperage, voltage and power. The power P is defined as energy spent per time. P = E/t, where the energy is I Joules, the time in seconds and the power in Watts, where a Watt is a Joule per ...
