The formula for power in watts is P = I . E where I is current and E is voltage or is it?
FACT1 : Voltage is the potential for current to flow.
Theory : Voltage is also called "potential difference" or " electromotive force". As with any measurement we need to have a standard point of reference for voltage that is 0V and another point of interest. The standard point of reference of 0V is earth. Voltage is measured between earth and any other point. However this is not the voltage we sh
