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. Bthe voltage across "B" is twice that across "A"
  3. Cthe 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.
