Question

An electric current moves through a circuit that makes a complete loop. How will the amount of electrical energy change as the current moves through the circuit?

a. The electrical energy will decrease throughout the wire because all energy eventually fades out.

b. The electrical energy will be the same at all points because energy is energy is neither created nor destroyed.

c. Electrical energy will decrease if it is converted into other forms, such as heat or mechanical energy.

d. Electrical energy might increase if the energy is used to move a device that increases the current.

Answer 1

c. Electrical energy will decrease if it is converted into other forms, such as heat or mechanical energy. As the electric current moves through the circuit, it may encounter resistances that convert some of its electrical energy into other forms, such as heat or mechanical energy. Therefore, the amount of electrical energy will decrease throughout the circuit.
