please give answer fast it's very urgent​

Answer 1

Explanation:

IM NOT SURE WHETHER THIS IS RIGHT, SO PLEASE DOUBLE CHECK.

B and C are connected in series.

So total resistance = B + C

= 4 + 2 = 6 ohms.

Now, B and C are connected in parallel to A.

So 1/total resistance = 1/A + 1/BC

= 1/12 + 1/6 = 3/12

Therefore total resistance = 12/3 = 4ohms
