Assume that V = 4.8V and I = 3.2mA. Find Ix in the figure using the principle of superposition.
2. Relevant equations
Kirchhoff’s Current Law
Kirchhoff’s Voltage Law
Total response = ∑responses from each individual source
3. The attempt at a solution
I believe I’m having trouble in simply solving for I_x in each circuit, but if you see any other mistakes please let me know.
Replacing the voltage source with a short circuit, we have:
Not really sure how to go about solving this one. If I had to guess, I would right a KCL at the bottom node such that:
I + the current across the 2k and 1k Ohm resistors = I_x
Replacing the current source with an open circuit, we have:
Summing the resistances now in series and solving for i_total:
4k * i_total = 4.8
i_total = .0012 A
If I’m not mistaken, this should be equal to I_x_2.
I_x = I_x_1 + I_x_2 = ?
