The value of current 'i' in the circuit = 13 A

Given:

I (PA) = 15 A

I (QB) = 3A

I (AD) = 8A

I (DS) = 5A

To find:

The current 'i' in the circuit

Solution:

When current flows in a closed circuit when current gets divided into two different circuits the sum of current flowing through these two is equal to the current from the source.

Current flowing through AB:

I (AB) = I (PA) - I (AD)

I (AB) = (15 - 8) A

I (AB) = 7 A

Current flowing through BC:

I (BC) = I (AB) + I (QB)

I (BC) = (7 + 3) A

I (BC) = 10 A

Current flowing through DC:

I (DC) = I (AD) - I (DS)

I (DC) = (8 - 5) A

I (DC) = 3 A

Current flowing through CR:

I (CR) = I (BC) + I (DC)

I (CR) = (3 + 10) A

I (CR) = 13 A

I (CR) = i

i = 13 A

The value of current 'i' in the circuit = 13 A
