The length of a conductor is halved. Its resistance will be _.
Correct answer: A. Halved
- A. Halved
- B. Doubled
- C. Unchanged
- D. Quadrupled
Explanation
Length of conductor is halved, the resistance will be halved too, both are directly proportional to each other.R = L/A

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.
