Question

N resistors each of resistance R when connected in series offer an
equivalent resistance of 50 ohm and when reconnected in parallel the
effective resistance is 2 ohm. The value of Ris
(a) 2.5 ohm (b) 5ohm (c) 7.5 ohm (d) 10 ohm
​

Answer 1

Answer:

10

Explanation:

nR= 50

n/R=2

ON SOLVING N= 10

Answer 2

Explanation:

nr = 50

n/r = 2

.r = n×2

r = 5x2

r = 10
