Questions
In the given circuit of fig.no current is passing
through the galvanometer connected to a meter bridge. Distance AC corresponding to null deflection of galvanometer is x. What would be its value if the radius of the wire AB is doubled ?
detailed solution
Correct option is C
When Wheatstone bridge is balanced, thenR1R2= resistance of AC part resistance of BC part When the diameter of the wire is doubled, the ratio of R.H.S. remains the same. Hence the value of ,AC (= x) remains the same,Talk to our academic expert!
