Q. |
A wire of resistance R is cut into ‘n’ equal parts. These parts are then connected in parallel. The equivalent resistance of the combination will be – |
A. | nR |
B. | R/n |
C. | n/R |
D. | R/n² |
Answer» D. R/n² | |
Explanation: Since R is directly proportional to length of the wire, when wire is cut into equal parts, then Resistance of each part = R/n |
