电力口诀(Power formula) Load current is estimated first 1. uses This is based on the power of electrical equipment (kW or kVA) to calculate the current (ANN) formula. The size of the current is directly related to power, voltage, and also don't rate (also known as power factor and so...
The basic equation to solve for power (P) when voltage (E) and current (I) are known is:P = E x Iwhere:P is the power in watts (W) E is the voltage in volts (V) I is the current in amperes (A)How to SolveTo determine the power using this formula, you multiply the ...
