Is current source also a voltage source?
No, a current source is not a voltage source.
I'm not going to mess with this "ideal source" terminology, it just makes things too complicated.
A current source "simply" supplies a SPECIFIED current. … There will be a voltage with the current, but that doesn't make it a voltage source.
Let's be a little specific and say it's a 1 Ampere current source, no matter what type of current. …

What are the limits of the Ebers-Moll model for large currents?
I learned that the Ebers-Moll equation Ic = Is(T) ∗ exp(Vbe/Vt) "predicts" the collector current to rise exponentially with the base-emitter Voltage. … Why is the current not increasing exponentially anymore?
What model explains this effect?
Thanks! …

Multiple AC-DC power supplies: one direct AC wall plug or two?
The overall power consumption of your devices is about (multiply voltage and current)
15 W + 60 W + 60 W + 48 W = 183 W
There will be additional conversion losses for the power supplies. … That will take 2 Amps of current from the 120 V wall outlet.
No matter if the wall outlet gives you 10 or 15 Amps, you will be safe drawing only 2 Amps.
Only one wall plug. …
