A) \[2\,\Omega \]
B) \[3\,\Omega \]
C) \[6\,\Omega \]
D) \[8\,\Omega \]
Correct Answer: D
Solution :
Let the value of shunt be r. Hence the equivalent resistance of branch containing S will be \[\frac{Sr}{S+r}\] In balance condition, \[\frac{P}{Q}=\frac{Sr/(S+r)}{R}\]. This gives \[r=8\Omega \]You need to login to perform this action.
