# Questions tagged [norton]

For questions about Norton's Theorem, which states that a linear network of impedances, voltage sources, and current sources can be replaced with an equivalent network composed of a current source in parallel with an impedance. Consider also using the "thevenin" tag for questions also involving its dual, Thévenin's theorem.

### How to solve Thevenin and Norton circuit?

This is the circuit for the problem in finding Vth and Rth. Analyzing this circuit yields Vab=−35V and Ia=0. If 10V is connected to Vab, then Ia=1.125A From what I remember, you need to short the ...

### Norton equivalent in sinusoidal RC circuit

I've been able to compute Iab, which is easy enough since the circuit short circuits when you connect A-B, but I couldn't find Req / Yeq. I'm analyzing the circuit as ((R1//R2)+C1)//C2). Is this wrong?...

### Thévenin's Theorem - What to do when ending up with a voltage source in paralell with one resistor?

I want to find the Thévenin and Norton equivalents for the circuit below. To find $R_{Th}$ we first kill all the sources. Then we have 2 paralell resistors, in series with one resistor and all of ...

### Resistor in parallel with a short circuit. Will current flow through it?

I'm trying to find the Isc of this circuit seen by the capacitor at t > 0 so I could find the Rth and get the circuit's time constant. If I make the capacitor a short circuit, it will be in ...
