Question:

The following statements are given related to Wheatstone Bridge:

(A) when Wheatstone Bridge is balanced, no current flows through the galvanometer arm.
(B) Wheatstone Bridge works on the principle of Kirchhoff's law.
(C) Being a null method based experiment, the result is free from the effect of extra resistances (cell resistance) of the circuit
(D) Wheatstone Bridge is most sensitive when all the four resistances are nearly of the same magnitude.
