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

  1. A "A" has half the resistance of "B"
  2. B the voltage across "B" is twice that across "A"
  3. C the voltage across "A" is twice that across "B"
  4. D "B" has half the resistance of "A"

Correct answer: A — "A" has half the resistance of "B". From the official ISED question bank, verified word for word.

Why

In a parallel circuit, both resistors share the exact same voltage. The full explanation — and one for every question — is in Pro.
