Question

Q. 10. In the circuit shown in the figure, find the total resistance of the circuit and the current in the arm CD.
​

Answer 1

Explanation:

BC and CD are in series and their combination is in parallel with AD

∴

R

1

=

6

1

+

3

1

or,R=2Ω

So, Total resistance of the circuit

R

T

=(2+3)Ω=5Ω

So, Net current I= R

V

= 5

15

=3A

I CD = 3

3+6

I=1A
