Question

calculate equivalent resistance.​

Answer 1

Step-by-step explanation:

The points C and E can be treated as same point as their potential difference is zero. Similarly, D and F are also same.

Now we have git a simple parallel combination of the 3 resistors of 20 ohm, 10 ohm and 20 ohm.

And this parallel combination is in series with the fourth resistor of 6 ohm.

Parallel combination:

1/R=1/20 + 1/10 + 1/20 = 4/20 = 1/5

So, R = 5 ohm

Net resistance:

Req = 5 + 6 = 11 ohm
