Question

1. Find the current in each branch of the circuit as shown in below figure, by using Kirchhoff's laws ​

Answer 1

Answer:

Step 1: Current in the circuit [Refer Fig.]  

There is no current in BE branch, so the potential difference across resistance R  

To find Potential difference between Points A and D, we can see a path ABED, such that, the branches AB and ED have batteries only and there is no current in branch EB.

Therefore, we can directly find the required potential difference without finding the current in all the branches.

Note: There is no need to apply KVL to find current in all the branches.
