Question

in the given figure find the equivalent resistance​

Answer 1

Two 3 Ohm resistance at the outer end are in series hence it becomes 6 Ohm

Now 6 Ohm resistance is in parallel with inner 3 Ohm resistance

so equivalent resistance becomes

$\frac{6 \times 3}{6 + 3} = \frac{18}{9} = 2 \: ohm$

Answer 2

Explanation:

I have done only rough work. So Equivalent resistance is 2 ohms
