Figure`6.52` shows a balanced wheatstone network. Now, it is disturbed by changing `P` to `11 Omega`. Which of the following steps will not bring the bridge to balance again?

A

increasing R by `2 Omega`

B

increasing Q by `10 Omega`

C

increasing S by `20 Omega`

D

making the product `QR=2200 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
The relatin `(P)/(Q)=(R )/(S)` or PS=QR should be satisfied by all.
