Question

Which of the following statements are true?

a) The potential energy of the charge carriers is increased when they move through the battery and decreased when they move through the load. b) In an electrical circuit, the energy from the power source is transferred to the load by net transport of charge carriers. c) In a single loop circuit, the energy of a charge carrier is decreased non-negligibly upon traversing the circuit once. d) The energy of the charge carriers is not changed when they travel through the wire.

Explanation / Answer

The energy of the charge carriers is not changed when they travel through the wire.

because Charge is neither created nor destroyed, and as such, the amount of charge which enters a light bulb in a second is equal to the amount of charge which exits the light bulb in a second. This quantity (charge per second) is the current and it is everywhere the same in a circuit.
