  • What is the maximum resistance which can be made using five resistors each of 1/5 Ω?  (a) 1/5 Ω (b) 10 Ω  (c) 5 Ω (d) 1 Ω

What is the maximum resistance which can be made using five resistors each of \frac{1}{5}\Omega ? 
(a) 1/5 \Omega
(b) 10 \Omega
(c) 5 \Omega
(d) 1 \Omega

Answers (1)

Answer: (d)
Solution:
Maximum resistance is obtained by connecting all the resistors in series.
Series combination of n equivalent resistors of R\Omega is (R\times n)\Omega
R_{s}=R\times n=(5\times1/5)\Omega =1\Omega
Therefore, option (d) is correct.
