Electrical Power in Circuits Electrical Power, ( P ) in a circuit is the rate at which electrical energy is absorbed or produced within a circuit. Learning physics formulas is important for exams because they provide a compact and precise way of expressing the fundamental concepts and laws of physics. When the force used in power settings is conservative, then the work done by this power results in a change of mechanical energy and as a result changes either the kinetic, potential or both types of mechanical energies in a system. Work is done when a force causes displacement, Energy is the ability to do work and Power is the rate at which work is done or energy is transferred.
