What is Energy transformed?
The potential difference between two points is the energy transferred per unit charge. An electrical circuit is an energy transformation device. Energy is provided to the circuit by an electrochemical cell, battery, generator or another electrical energy source. Energy is delivered by the circuit. The rate at which this energy transformation takes place has a great relevance to the design of an electrical circuit for useful functions.
Energy transformed equation
To calculate Energy transformed we use this equation.
Energy = power x time
$ {\mathit E \, \text = \mathit P \mathit t}$
Energy = charge flow x potential difference
$ {\mathit E \, \text = \mathit Q \mathit V}$
