Does any Independent source a Linear element?

As far as I know the linearity of any element is given by the superposition principle meaning if it satisfy the superposition principle therefore its a linear one Meaning if $$f(x_{1})=y_{1}$$ and $$f(...

Do I consider the 50 Ω resistor on right side when 5 A is being open-circuited in superposition?

When I consider the 10 A as the source and change the 5 A to open circuit, is the 50 ohm resistor still being considered and become in series with the 100 ohm resistor? Same with when I consider the 5 ...

How to solve for \$v_0\$ in this circuit using superposition, and node-current method?

I'm probably missing something trivial but I'm banging my head over this problem for a few hours already. I think what throws me off is the dependent current source behavior when we are shorting E2, ...

Using Kirchoff's Laws instead of The Superposition Theorem?

So my textbook introduced The Superposition Theorem, and, to me, applying a combination of Kirchoff's Current and Voltage Laws seems to simplify the process for solving for the current or voltage of ...
