Question

A boy has five resistance of 1/5 ohm each. The maximum resistance that can be formed with them is; 1) 0.5 ohm; 2) 1 ohm; 3) 1/25 ohm; 4) 1/5 ohm

Answer 1

Hellow mate,

1 ohm is the answer

Answer 2

The answer to this question is option 2) 1 ohm. Arrangement:-
Req= R¹+R²+R³+R⁴+R^5
= 1/5+1/5+1/5+1/5+1/5
= (1+1+1+1+1)/5
= 5/5
= 1 ohm

Hope this helps you!
