In a typical Wheatstone network, the resistances in cyclic order are `A = 10 Omega, B = 5 Omega, C = 4 Omega` `D = 4 Omega` for the bridge to be balanced

Options

A. `10 Omega` should be connected in parallel with A
B. `10 Omega` should be connected in series with A
C. `5 Omega` should be connected in series with B
D. `5 Omega` should be connected in parallel with B

Answer

A

Explanation

`A/B = D/C rArr 10/5 ne 4/4`
`rArr A^(.)/B = D/C rArr A^(.)/5 =4/4 = A^(.) = 5 Omega`
`10 Omega` resistance should be connected in parallel with A resistance.
