D) only depends on the total current

Question

Quizplus · Accepted Answer

The power dissipated by any branch of a parallel circuit depends on both the voltage drop across the resistor (which is the same as the circuit voltage in a parallel circuit) and the value of the resistor. This relationship is described by the formula P = V^2/R, where P is power, V is voltage, and R is resistance. Therefore, both voltage and resistance are important factors in determining the power dissipated by a branch in a parallel circuit.
