Answer 1

This is your Example

due to wheatstone's network.

current through G is zero circuits will look like as shown.

total resistance is

9+6

9×6

Ω+.4Ω=3.6Ω+.4Ω=4Ω.

current i=

4Ω

6V

=1.5A

current i

1

bu using current division

i

1

=

9+6

9

×i=

15

9

×1.5=.9A

similiarly, i

2

=

6+9

6

×i=

15

6

×1.5=.6A
