Question # 1

Why does no current pass through Galvanometer in a balanced wheat stone bridge although the keys in the circuit are closed ?

  • Ans 1: No current pass through the galvanometer when wheat stone bridge is balanced.Because at this stage ,both the terminals of the galvanometer are at the same potential.Hence no current will flow through it.

Question # 1

Define Electromotive force and Terminal potential difference.

  • Ans 1: Electromotive force:The energy supplied to a unit charge in moving it from negative to positive electrode inside the source is called electromotive force.
  • Ans 2: Terminal potential difference:The potential difference across the terminal of a cell or battery when current is being drawn from it is called terminal potential difference.The potential difference across the conductor is zero when no current flows through it.
