Question

What will be the current in arm PQ of a circuit.
​

Answer 1

Answer:

The current in arm PQ of a circuit is i2+i3

Explanation:

To find: PQ portion of a circuit in terms of current flows.

Given : AB =I1 ,BD= I2 ,BP =I3

We have to find PD to find the current in the arm PQ

According to Kirchhoff law of current states that the total amount of current entering in junction or a node equal to the charge which is leaving the node.

PQ=BP+PD

So, the Net current loss is zero

According to the picture ,

I1=I2+I3 [AB=I1, BD=I2 ,BP=I3]

The amount of current through BD =PD [according to the law]

So, PD=I2

It is known that ,PQ=BP+PD

                           PQ= I3+I2

As the total amount current entering is equal to the junction or nodes leaving the circuit .

Here PQ  is leaving the node and is equal to the addition of BP&PD.
