Question

What is the maximum resistance which can be made using five resistors each of 1/5 Ω?

Options

• 1/5 Ω

• 10 Ω

• 5Ω

• 1Ω

Answer 1

1Ω

Explanation -

Resistance will be maximum when all the five resistors are connected in series. 

`"R"_("max") = 1/5 + 1/5 + 1/5 + 1/5 + 1/5`

`"R"_"max" = 1Ω`
