The effects of bends in a wire on its electrical resistance are:
Correct answer: A. No change
- A. No change
- B. Smaller
- C. Larger
- D. None of These
Explanation
In certain cases, small bends in a wire might not significantly alter its electrical resistance, especially if the wire is made of a highly flexible material or if the bends are not severe. However, this outcome depends on various factors, and there could be some change in resistance, but it might be negligible.

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.
