Answer:
Electric current is flow of electrons in a circuit.
Explanation:
Wires are made up of conductors such as copper or aluminum. Atoms of metal are made up of free electrons, which freely move from one atom to the next. If an electron is added in wire, a free electron is attracted to a proton to be neutral. Forcing electrons out of their orbits can cause a lack of electrons. Electrons, which continuously move in wire, are called Electric Current.
Heat is warmth that can be given off by a heat source such as a fire or space heater.
