Two resistors of 3 Ω and 6 Ω are joined in parallel. The equivalent resistance is:
- a9 Ω
- b2 Ω
- c4.5 Ω
- d18 Ω
Original Khojo Papers practice question — not from a past board paper.
Answer
2 Ω
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
For two resistors in parallel R = (3 × 6) ÷ (3 + 6) = 2 Ω, which is always less than the smaller of the two.
