Quizplus · Accepted Answer

The number of independent equations in any circuit equals the number of branches. This is because each branch can have its own unique current, and according to Kirchhoff's laws, each branch contributes to the overall behavior of the circuit, necessitating an equation to describe its electrical properties (emf, resistance, and current).
