Question

At any junction, what does Kirchhoff's Current Law state?

Options

• The sum of potential differences in a closed loop is zero

• The sum of currents entering equals the sum of currents leaving

• The total emf is always zero

• The current entering is always greater than the current leaving

Answer 1

KCL states that the sum of currents entering a junction equals the sum of currents leaving it. This expresses conservation of charge at the junction.
