A conducting wire of resistivity' p is cut into two equal parts. The resistivity of each part will be:
Correct answer: A. The same
- A. The same
- B. One fourth
- C. √2 times
- D. Halved
- E. Doubled
Explanation
When a conducting wire is cut into two equal parts, the resistivity (ρ) of each part remains the same. Resistivity is an intrinsic property of a material and does not depend on the size or shape of the object. So option A is the correct answer.

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.
