Question

What is loop law?

Accepted Answer

Loop law, also known as Kirchhoff's voltage law, states that the sum of the voltages in any closed loop in a circuit is zero.

Loop law is a fundamental principle in electrical engineering.
It is also known as Kirchhoff's voltage law (KVL).
According to loop law, the algebraic sum of the potential differences (voltages) around any closed loop in a circuit is always zero.
It is based on the principle of conservation of energy.
Loop law is used to analyze and solve complex electrical circuits.
It helps in determining unknown voltages or current flows in a circuit.
Loop law is applicable to both DC and AC circuits.
An example of loop law application is analyzing a series-parallel circuit with multiple resistors and voltage sources.
By applying loop law, one can calculate the voltage drops across each resistor and the total current flowing in the circuit.
