Questions tagged [voltage-source]
Anything related to voltage sources, their circuit models and their practical circuit implementations. An ideal voltage source is a two terminal device whose output is a voltage signal with a given waveform regardless of its load, i.e. irrespective of the circuit to which is connected.

What is the difference between a source and an active component?
I am having trouble forming a clear definition for a source component versus an active component. From my understanding, an active component is one which can supply power to a circuit, but may also ...

RC circuit with DC source: Kirchhoff’s law, voltage directions, and current flow convention
I am creating a video in Manim about basic electrical circuits. The circuit under consideration is an ideal RC circuit with a DC voltage source, no energy losses. My reasoning is as follows: When the ...

Does Thevenin apply to AC circuits in the same way?
I was in the lab and measured the analogue voltage at the output of an RC filter VF4 (top circuit). I now want to do simulations with these measurements to see how loading this voltage affects it. I ...

Input voltage in voltage-following op amp
I've recently learned about voltage-following op amps in class but I didn't understand what they were for, so I decided to do a bit of research. After watching a couple videos I now understand their ...

Limit reached without current at the limit on an SMU?
I have a Keysight B2900 series SMU and one of the channels is orange. By the manual, it is said that an orange display means that the current limit is reached. But the measured current (less than 1 nA)...

Linearity of dependent voltage source (from Hayt - 8th edition)
Here is a statement from Hayt "Engineering Circuit Analysis" 8th edition, page 124. "By a 'linear voltage-current relationship' we simply mean that multiplication of the current through ...

Do the controlling voltages or currents act independent of the existence of a dependent source?
Dependent sources confuse me. We were taught a method using input and output resistances to find out whether a dependent source is VVVS, VVCS, CCVS, CCCS. Apparently for a voltage controlled source if ...
