Question 15: Current Electricity

Question

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

Accepted Answer

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