Can a high-precision, low-current voltage source "fix" drift in a lower-precision, high-current current source?
I'm trying to generate a current source which is extremely low drift but can maintain high current (3A into a few ohms), that should be similar to this expensive high-precision current source.
However,...

Why isn't source transformation working here?
Doing it normally you would get the answer of 2320 mW (a 4 V drop across the current source).
However, for this question I had done a source transformation to a 1 V source,
then I added the two ...

What does a voltage or current source actually output?
Current is the rate at which electrons flow through a circuit, and voltage is the potential "drop" between two points in a circuit.
Do voltage sources output an unknown current, and vice ...

Why is there a negative source voltage when the MOSFET is off in this buck converter?
This is the voltage source. As you can see, when there is a turn-off phase, I have a negative source. Why?

Potential difference with ground
I think the potential difference (top) between the voltage sources is either 6V (15-9) or 15V (the bigger one wins?).
The potential difference between the resistor and V1 is -15V.
Is this correct?
