- D. None of these
Explanation
Kirchhoff's second rule, or Kirchhoff's voltage law (KVL), states that the total voltage around any closed loop in a circuit must sum to zero. This principle is based on the law of conservation of energy, which asserts that energy cannot be created or destroyed, only transformed from one form to another. In the context of electrical circuits, KVL reflects the conservation of energy by ensuring that the sum of the potential differences (voltages) around a closed loop equals zero, indicating that the electrical energy gained and lost around the loop must balance out.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
