Question

Kirchhoff's Voltage Law (KVL) states that around any closed loop:
  1. A
    Sum of currents = 0
  2. B
    Sum of EMFs × resistances = 0
  3. C
    Sum of EMFs = sum of IR drops
    Correct
  4. D
    Power is zero

Correct answer

Sum of EMFs = sum of IR drops

Explanation

KVL: ΣE = ΣIR in any closed loop. It follows from energy conservation (electric potential is path-independent).
