Answer 1

Kirchhoff’s Voltage Law applied to a loop deals with the conservation of energy.

Explanation:

Kirchhoff’s Voltage Law (KVL) states that the sum of all electrical potential differences (voltages) around any closed loop in a circuit is zero.

Since voltage is defined as electric potential energy per unit charge, moving a charge around a complete loop and returning to the same point means there is no net change in its potential energy. Therefore, KVL is a direct consequence of the law of conservation of energy.
