Question

if a wire is connected when point a and b how much current will through that wire​

Answer 1

Answer:

As the bridge is not balance so the current will through wire.

The current through arm PAQ is I

1

=V/(4+4)=V/8

The current through arm PBQ is I

2

=V/(1+3)=V/4

Thus, V

A

−V

Q

=4I

1

or V

A

−0=4(V/8) (as Q is connected in ground )

or V

A

=V/2

V

B

−V

Q

=3I

2

or V

B

−0=3(V/4) (as Q is connected in ground )

or V

B

=3V/4

since V

B

>V

A

so current flow from B to A.
