Homework Statement
Find I in the circuit using the superposition principle
Homework Equations
superposition:
I = i_1 + i_2 + i_3
The Attempt at a Solution
for i_1 we neglect the 12V and the 4A sources:
(8 + 2 + 6)i_1 - 16 = 0
i_1 = 1A
for i_2 we neglect the 16V and the 4A sources:
(8 + 2 + 6)i_2 + 12 = 0
i_2 = -0.75
i don't actually know how to solve for the current in i_3:
since there are two nodes only i use parallel resistors:
6 + 8 = 14ohms... and 2 ohms are parallel
1/14 + 1/2 = 1/R
R = 1.75
current source = 4 A
so the current source and 1.75 are in parallel... so what i need is to solve the outer current,i_3
now I am really stuck can someone help pls
ans. I = 0.75A
