In my electronics journey I've seen people mention spice and I've never known what they were talking about.
How are you giving away all this information for free? This is absolutely the highest quality electronics education. Thank you so much

[acestudioscouk-Ace-GACE]

Just the video I needed as a newbie to LTSpice, thank-you! I've subscribed.

[edwardvanravesteijn]

Thanks for the clear explanation AND the tip for entering G for Ground :-)

[mnada]

I like to watch a video a day from this channel. Thanks

[davidstonier-gibson]

Thank you. Retired old goat .. ehr ... pro dipping my toes into simulation. Just a nice little getting started tute, just what I needed. And no duffa duffa music - brilliant!

Helpful. I did some math on making a custom power supply card for an old device. I was going to assemble a prototype on a breadboard but I think I'll try LTspice out to verify instead. TY :)

The Windows version is a lot more 'Busy ' if you know what I mean ! thanks for your tutorial as it does get you up and running...cheers.

I don't get the oscilloscope when I click run. LTSpice shows a text file with the values for each component instead?

Output:
--- Operating Point ---

V(n002): voltage
V(n001): 5 voltage
I(R1): device_current
I(R3): device_current
I(V1): device_current

Thanks for the video.
PWL is PieceWise Linear.

it is full of bugs: simulate 5 diodes of different models where each model has its own band-gap voltage (Eg parameter). All 5 IV curves overlap: model card cannot differentiate based on Eg.

I'm new to LTSpice and got a question. When I execute dc operating point analysis (.op), i don't want a time dependent graph but rather values of currents/voltages written directly. And this is what i see on the tutorials of the windows version. Is it also possible in mac?

[andym]

How to glue it together and turn it on - exactly what I was looking for.

[daz]

looks like an interesting programme :) is there a download link :)

[worm_hole]

why isn't voltage 5v at 6:45? when i simulate it by myself i find 5v

[brianaull]

I noticed you have a three-button mouse on your Mac. I find that if I try instead use control-click on my trackpad to do a right click, this works when adding a component, but fails when using the pointing finger cursor to edit a component.

[averagejoe]

Still not sure how to measure total circuit resistance in a circuit using this program. =(

[nigeltrueman]

I downloaded LTspiceXVII and it seems to have many differences to what you are using to the point where I couldn't work out how you measured voltages across components, so it was not as useful as it could have been.

[Andrew-dfey]

Pls make more videos about electrical engineering.

[robertmccully]

have not dug into it yet, buy can you open and close switches during a simulation?

[nigelhungerford-symes]

It seems like every ee cad tool's UI is updated every week so this tutorial is not matching what I see in May 2021. I get a one shot analysis, not a real time meter style
