Question

Quizplus · Accepted Answer

The number of independent loop equations in a circuit can be determined using Kirchhoff's circuit laws. According to Kirchhoff's voltage law (KVL), the number of independent loop equations is given by B - J + 1, where B is the number of branches, and J is the number of junctions in the circuit.
