- AThe charge flowing in an electric circuit is conserved.
- BThe energy in an electric circuit is conserved.
- CThe sum of the electric currents entering a point in an electrical circuit is equal to the sum of the electric currents leaving that point.
- DThe sum of the potential differences in a circuit is equal to the sum of the products of the current and resistance.
