Question

1. kirchhoffs voltage law states:

a all voltage sources equal the voltage drops
b in a loop, all voltage sources equal voltage drops.
c in a loop, the algebraic sum of the voltage drops and voltage sources equals zero.
d the sum of the currents into a point equals the sum of the currents out of the point.

Explanation:

Kirchhoff's Voltage Law (KVL) states that in any closed - loop network, the algebraic sum of all the voltage drops and voltage sources is zero. Option a and b are imprecise statements. Option d is about Kirchhoff's Current Law (KCL), not KVL.

Answer:

C. In a loop, the algebraic sum of the voltage drops and voltage sources equals zero.
