Two resistors are in parallel. Resistor "A" carries twice the current of resistor "B," which means that:
- A"A" has half the resistance of "B"
- Bthe voltage across "B" is twice that across "A"
- Cthe voltage across "A" is twice that across "B"
- 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.
