Four 20-$\Omega$ resistors are connected in parallel and the combination is connected to a 20-V emf device.The current in any one of the resistors is:
A)0.25 A
B)1.0 A
C)4.0 A
D)5.0 A
E)100 A

Question

Quizplus · Accepted Answer

In a parallel circuit, the voltage across each resistor is the same as the source voltage. Using Ohm's Law (V = IR), the current through one resistor is I = V/R = 20V/20Ω = 1.0 A.
