Question

8
You are given several identical resistors each
of value 5ohm and each capable of carrying a
maximum current of 2A. It is required to make a
suitable combination of these resistances to produce
a resistance of 2.522 which can carry current of 4A.
The minimum number of resistances required for
this job is
1) 2
2) 4 3) 6 4) 8​

Answer 1

Answer:

option -d

Explanation:

R'=R/4

as per given criteria R/4=5 ohm

R=20 ohm

so therefore 2resistors should be connected .

hence oral no. of resistors=8
