Final answer:
Kirchhoff's voltage law states that the total voltage drop in a circuit is equal to the sum of the voltages. The sum of the voltage drops across all the components in a circuit is equal to the voltage supplied by the source.
Step-by-step explanation:
According to Kirchhoff's voltage law, the total voltage drop in a circuit is equal to the sum of the voltages. Kirchhoff's voltage law states that the algebraic sum of the potential differences (voltages) in any closed loop or mesh in a network is always zero. This means that the sum of the voltage drops across all the components in a circuit is equal to the voltage supplied by the source.
