Question

resistance between A to B and current in 3 ohm​

Answer 1

Answer:

12.2 ohm

Explanation:

since 2 and 3 are parallel

so 1/r = 1/2 + 1/3

r = 6/5 ohm

now 4+7+6/5 are in series

so r= 61/5 = 12.2 ohm

V=IR

V= 10 x 61/5

V= 122 volts

V in 7 ohm = 10x 7 = 70 v

V in 4 ohm = 10x 4 = 40 v

V in 3 ohm = 122-(70+40)= 12V
