Question

In the given network....find resistance between A and B

Answer 1

Answer:

In the given ciruit, the two 1 ohm resistors are connected in series.

So, they can be replaced with a resistor of equivalent resistance.

Req = 1 + 1 = 2 ohms (as they are in series)

So, both the 1 ohm resistors can be replaced by a 2 ohm resistor.

Now, the three two ohm resistors (2 in the figure, and 1 which we just added by replacing the 1 ohm resistors),

are in parallel

So, there equivalent resistance = (1/2 + 1/2 + 1/2)^-1

= (3/2)^-1

= 2/3 ohms.

Therefore, the equivalent resistance between A and B is 2/3 ohms
