The length of the wire is doubled. Its conductance will be:
Correct answer: B. Halved
- A. Unchanged
- B. Halved
- C. Doubled
- D. 1/4 of the original value
Explanation
This option correctly states that doubling the length of the wire will halve its conductance. As explained earlier, when the length of the wire is doubled, its resistance also doubles. Since conductance is the reciprocal of resistance (G=1/R), doubling the resistance will halve the conductance. Therefore, option B is correct.

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.
