The combined equivalent resistance across the main line in a parallel circuit can be found by dividing the common voltage across the parallel resistances by the total current of all branches.

Question

Quizplus · Accepted Answer

In a parallel circuit, the voltage across all branches is the same, and the total current is the sum of the currents through each branch. The equivalent resistance can indeed be found by dividing this common voltage by the total current, according to Ohm's law (V = IR).
