What is the purpose of Kirchhoff's Voltage Law (KVL)?
A. The sum of all voltages in a closed loop equals zero
B. The sum of all currents in a closed loop equals zero
C. The total resistance in a network is constant
D. The sum of all power losses in a loop equals zero
Explanation:
Kirchhoff's Voltage Law (KVL) states that the sum of all voltages around any closed loop in a circuit must equal zero, meaning energy is conserved in a loop.
