Three resistors, 10 $\Omega$, 10 $\Omega$, and 10 $\Omega$, are wired in parallel and connected to a 120-V battery. How much current flows in this circuit?

Question

Quizplus · Accepted Answer

In a parallel circuit, the total resistance (R_total) is given by 1/R_total = 1/R1 + 1/R2 + 1/R3. For three 10-ohm resistors, R_total = 10/3 ohms. Using Ohm's Law (V = IR), the total current (I) is V/R_total = 120/(10/3) = 36 A.
