Current Electricity Charging Discharging Of Capacitors Question 224

Question: Which is a wrong statement

[MP PMT 1994]

Options:

A) The Wheatstone bridge is most sensitive when all the four resistances are of the same order

B) In a balanced Wheatstone bridge, interchanging the positions of galvanometer and cell affects the balance of the bridge

C) Kirchhoff’s first law (for currents meeting at a junction in an electric circuit) expresses the conservation of charge

D) The rheostat can be used as a potential divider

Show Answer

Answer:

Correct Answer: B

Solution:

In balanced Wheatstone bridge, the arms of galvanometer and cell can be interchanged without affecting the balance of the bridge.
