a law showing that electric charge is conserved around an electrical circuit: - At any point in an electrical circuit where charge density is not changing in time, the sum of currents flowing towards that point is equal to the sum of currents flowing away from that point
a law showing that energy is conserved around an electrical circuit: - The directed sum of the electrical potential differences around a circuit must be zero
(physics) two laws governing electric networks in which steady currents flow: the sum of all the currents at a point is zero and the sum of the voltage gains and drops around any closed circuit is zero
