Question

Find the equivalent resistance between A & B in the given circuit.

• A. 2 Ω
• B. 6 Ω
• C. 14 Ω
• D. 15 Ω

Answer 1

The correct option is B

6 Ω

The resistors on the right most sides are in series

So, they can be replaced with their net resistance which will be 2 + 2 + 2 = 6 $\Omega$ which is in parallel with 3 $\Omega$.

Resistors 6 $\Omega$ and 3 $\Omega$ are in parallel, which will be 2 $\Omega$

So, the circuit reduces to

Repeating the same process, we get the net resistance across AB, which will be 6 $\Omega$
