MCQ
Which of the following statements is false?
  • A
    Wheatstone bridge is the most sensitive when all the four resistances are of the same order of magnitude
  • In a balanced wheatstone bridge if the cell and the galvanometer are exchanged, the null point is disturbed.
  • C
    A rheostat can be used as a potential divider
  • D
