Thanks, that makes sense. I looked through all of the symbols under sym but neglected to review the nested folders like misc.
Thank you. I believe this would model a battery charging circuit then? I can't imagine any other reason for the second voltage. source.It is a voltage source, the same as V1 in you schematic but with a different symbol.
It is shown as a single cell battery symbol, to indicate that it usually represents a DC voltage source, but it can be specified for any type of voltage output, as can V1.
No. it is not a charging circuit.Thank you. I believe this would model a battery charging circuit then? I can't imagine any other reason for the second voltage. source.
Apparently, someone has edited (removed) the original question posted by the TS, that basicall asked what is the function of the circuit in post #1.hi @eetech00
Refer his old thread.

Nevertheless, my reply in post #8 is completely relevant (and accurate to the title of the thread) to the response from the TS.hi @eetech00
I have checked and cannot find any record showing an Edit or Deletion of the TS threads or posts.
All editing or changes are logged on the site.
I would like to see any evidence of the alleged editing, and will look into it further.
Moderation.
Hi Eric, may I ask why that would be necessary/different from simply measuring the current through the thermistor U1?hi mike,
As the basic Cell has no internal resistance and the V=0 it is often used as a convenient way of measuring the current through a circuit without interfering with the circuit's operation.

Inserting a zero-voltage voltage source is a very common technique for doing current-sensing in a simulation.Thank you. I believe this would model a battery charging circuit then? I can't imagine any other reason for the second voltage. source.
It's not necessarily necessary, just a common technique that many people use as standard practice. One utility that it has is of decoupling the current-sensing function from the circuit topology, allowing you to make arbitrary changes to the circuit and just move your current-sensing source to the place you want to measure the current and your waveform displays don't need to be changed. You can also capture the data to a file for post processing and because the device name remains the same, you don't have to change anything in whatever tool you are using to do the post processing.Hi Eric, may I ask why that would be necessary/different from simply measuring the current through the thermistor U1?
