Energy is equal to current times time

WebBut Q over T is just the current, so I get that the power is going to equal the current through that resistor times the voltage across that resistor. And this is the formula for electrical power. This tells you how many joules of thermal energy are being created in that resistor per time. WebElectric Potential Difference. The electric potential difference between points A and B, V B − V A, is defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta. 1 V = 1 J/C.
