Question no
21 first one , find resistance between A and B please

Answer 1

Lets turn abc into a straight line
so the total resistance in that line is 2+2 = 4ohm

now abc is in parallel to ac
so 4ohm and 4ohm are in parallel

R1 = 4
R2 = 4

1/R(eq) = 1/R1 + 1/R2 = 1/4 + 1/4 = 1/2

===> R(eq) = 2 ohm.

2ohm is the answer. Please mark as brainliest!

Answer 2

Resistance between A & B :

Rs = 2 + 2 ohm = 4 ohm

1\Rp = 1\4 + 1\4 = 2\4 = 1\ 2
Rp = 2 ohm

Hence, resistance between A & B = 2 ohm

Hope it helps!!
