Question B-005-005-010

Two resistors are in parallel. Resistor A carries twice the current of resistor B, which means that:

Correct Answer

A has half the resistance of B

Explanation

In parallel, voltage across both resistors is the same (V). Current (I) = V/R. If I_A = 2 * I_B, then V/R_A = 2 * (V/R_B). Dividing by V gives 1/R_A = 2/R_B, or R_A = R_B / 2.
