MCQ
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.
  • Wheatstone bridge is susceptible to high dc current.

Answer

Correct option: D.
Wheatstone bridge is susceptible to high dc current.

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.
