​Power is a measure of the rate of energy transfer in relation to the the voltage and current in a circuit. It is measured in Watts(W)

​​Power

​

​Voltage is the pressure from a power source in an electrical circuit that pushes charged electrons through a conducting loop. Measured in volts(V)

​​Voltage

​

The stream of charged electrons moving through a conductor. Relative to voltage(V) and impedance(Z).

Measured in amps.​
