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

Options:

Answer:

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 $3Ω$ resistance in $B D$ arm is ineffective and can be omitted from the circuit. Hence, equivalent resistance remains same when $3Ω$ resistor is removed.
