How to calculate electrical resistance
WebElectrical energy is the product of power multiplied by the length of time it was consumed. So if we know how much power, in Watts is being consumed and the time, in seconds for … WebElectrical Energy Equation: We can use any of the following equations to find the power dissipated by a resistive circuit element. P = V I = I 2R = V 2 R P = V I = I 2 R = V 2 R. Where: P = Power dissipated in a resistive element in watts. V = The voltage drop across the resistive element in volts. I = The current through the resistive element ...
