Question

State sign convention of Kirchhoff's voltage law.

Answer 1

1. When a resistor is traversed in the direction of conventional current during a loop, the potential difference (p.d.) across the resistor is regarded as negative. The resistor's potential difference is positive if we cross it in the opposite direction of the current flowing through it.
2. When a loop is being completed, the emf of a cell is interpreted as positive if it is traversed from its negative terminal to the positive terminal, and as negative if it is traversed in the opposite direction.
