If a wire of resistance 10 ohms is cut into 5 equal parts, what is the resistance of one part?
50 ohms
2 ohms
10 ohms
5 ohms
Correct Answer: B — 2 ohms
Explanation:
When a wire is cut into equal parts, the resistance of each part equals the total resistance divided by the number of parts. 105=2\frac{10}{5} = 2510=2 ohms.
