Introduction to Electric Energy and Power

Within an electric circuit as illustrated in the figure below, energy is supplied by a battery,
which uses energy from the potential energy (PE) stored in its chemical reactants.
Circuit-5

Whenever PE is lost, kinetic energy (KE) is gained by the electrons.
Subsequently, KE is converted to heat due to collisions with other electrons and atoms.
So, energy source ⇒ PE ⇒ KE ⇒ heat.
