Q

BITSAT-Five identical resistors of resistance 1 ohm each, are connected along the four edges and one of the diagonals of a square.

 A potential difference of 1V is applied across the other diagonal. What will be the current in the resistor along the diagonal?

  1. 0.5 A

  2. 1 A

  3. 5 A

  4. Zero

By closely observing at the figure, you will find that this circuit is a balanced wheat stone bridge.

Hence no current will pass through the diagonal.

Option (4) is correct
