Question

Find the false statement.

(a) Wheatstone bridge is analogous to simple level system

(b) A galvanometer with low resistance in series is an ammeter

(c) Wheatstone bridge cannot be used forprecision measurement because of the error introduced in contact resistance

(d) Wheatstone bridge is susceptible to high dc current

The question was posed to me in final exam.

Question is from Wheatstone Bridge topic in chapter Current Electricity of Physics – Class 12

Answer 1

Right choice is (d) Wheatstone bridge is susceptible to high dc current

To explain: The false statement is Wheatstone bridge is susceptible to high dc current. It is actually not susceptible to high dc current and can give inaccurate readings if not balanced. The Wheatstone bridge measures resistance from few ohms tomega ohms.All the other statements are valid.
