In the following circuit diagram, when 3 resistor is removed, then equivalent resistance of the network

Options

  1. Aincreases
  2. Bdecreases
  3. Cremains same
  4. DNone of these

Correct answer

C. remains same

Step-by-step solution

The equivalent Wheatstone's bridge network of the given circuit is shown in figure. Here, The points B and D are at the same potential as the bridge is balanced. So, the 3 resistance in B D arm is ineffective and can be omitted from the circuit. Hence, equivalent resistance remains same when 3 resistor is removed.
