Question

the current flowing through branch BD for the given circuit will be

Answer 1

concept of Kirchoff laws

Answer 2

It is a simple question

Since it is given in parallel the voltage would be same but the current would be different

Here the current flowing through BD would be I 1 + I2 and the voltage would be the net difference between the voltage supplied by the two ends of the circuit so

V(net)=V2-V1

=30-15

=15

By Ohm's law

V=IR

15=Ix3

I=15/3

I=5A
