Question : 113 of 199

Marks: +1, -0

What will be the value of current

l_4

(in A) for the diagram given below?

Solution:

At node C,

I_3 = I_1 + I_2

= 1 + 3 = 4 A
At node A,

I_7 = I_8 + I_9

= 1 + 1 = 2 A
At node B,

I_4 + I_3 = I_5 + I_6 + I_7

∴ I_4 + 4 = 2 + 1 + 2

∴ I_4 = 5 - 4

∴ I_4 = 1 A
