A wire of resistance 24 Ω is cut into three equal parts, and all parts are connected in parallel. The equivalent resistance is:
Correct answer: B. 3Ω
- A. 2Ω
- B. 3Ω
- C. 8Ω
- D. 24Ω
Explanation
Each part has resistance 24/3 = 8 Ω. For three parts in parallel: 1/Rₑ𝑞 = 1/8 + 1/8 + 1/8 = 3/8, so Rₑ𝑞 = 8/3 ≈ 2.67 Ω, closest to 3 Ω.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
