5.A piece of copper wire is cut into ten equal parts.These parts are connected in parallel. The jointresistance of the parallel combination will be equalto the original resistance of uncut wire, multiplied bythe factor of(1) 0.01

Answer»

If copper wire of Resistance R cut into 10 equal part then resistance of one piece is = R/10

Hence,All 1p pieces are connected in parallel hence equivalent resistance 1/R1 = 10(1 / R/10)1/R1 = 100/RR1 = R/100R1 =.01R

(1) is correct option
