Hi, can anyone recommend a free circuit simulator software for beginners that works on Windows platform?
Thanks SamR. I am very new here. I'll check it out. Thanks again.You will find a lot of LTSpice users here and some KiCad and the occaisonal Falstad. All free. My preference is LTSpice.
+1 for LTspice.Thanks SamR. I am very new here. I'll check it out. Thanks again.
Thanks for the response. I have some experience in troubleshooting electronic circuits but not in design. Perhaps you could tell me from where I can get the fundamentals right. I downloaded LTSpice XVII and found another in the Microsoft Store called DrawLogix. I need to take the learning and the simulation together, a bit of reverse engineering to help me along the way.Welcome to AAC!
+1 for LTspice.
Simulators have their place, but I suggest that you learn the fundamentals before relying on a simulator. Otherwise, you run the risk of becoming too dependent on the simulator and not being able to design circuits without one.
I'm old school. I like to use the simulator between my ears. If I'm too lazy to breadboard the circuit, or don't have the parts, I'll run a simulation. I haven't used LTspice enough to be able to use it's capabilities well. I once tried simulating a linear regulator being used as a switching regulator and LTspice was very picky about the component values that would work and was overly pessimistic on switching noise. When I breadboarded the circuit, all component values I tried that wouldn't simulate worked and output ripple was significantly lower.
For digital, I use Digital Works, it's free from here. It has its limitations and is no longer being maintained, but the price is right and I only recall encountering one unreproducible bug. I use it for the same reasons I use LTspice.
Nothing is going to beat learning it in a school setting. You need someone giving you the theory, in a logical order, and being able to tell when you're not getting it; either through tests or looking at your eyes gloss over from confusion.Perhaps you could tell me from where I can get the fundamentals right.
Ok SamR. I'll see how it goes.There is a bit of a learning curve getting started with LTS and more to become truly proficient at it. Which I am not. It's kinda funky at first but it grows on you. It does not produce "standard" schematics but what it does do is pretty amazing.
Ok dl324, I do have a formal education but no practical experience in designing. I don't need to be a designer but I want to study schematics to understand how each component functions in the circuit. That at the moment, helps me with troubleshooting faulty PCBs and later, design if I get good at it.Nothing is going to beat learning it in a school setting.

Some people can self teach, but the vast majority will need a more formal education.
If you use YouTube videos and the internet for your information, you'll be at a serious disadvantage because you won't likely be able to tell the difference between what's good and what's bad. There are a lot of YouTube videos that supposedly explain things at a glacial pace when, in reality, they don't know much and are just trying to monetize your time.
Sure, I'll take a look. Thanks.Not to detract from the votes for LTspice, have a look at KiCad that also has simulation capabilities.

Depending on how many years it has been since you took classes and how much practice you've had since then, you may have a lot of review ahead of you. I didn't do much coding for a few years after I retired and was shocked, and disappointed, with how much I had forgotten. It seemed like it took forever to get back to anywhere near the level I was at when I used those skills daily; though it was probably more like 3-6 months. It was frustrating as all get out to have to relearn how to do things I knew I used to be able to do (kind of like what Microsoft does to me with every OS release).Ok dl324, I do have a formal education but no practical experience in designing.
I never did practice while I was in college. I have a degree in Applied Electronics and Instrumentation but the fact is I was forced into college, dropped out and went back again. Never interested in the college lab and somehow managed to pass exams just for the sake of having the degree. But things changed when I got a job in maintenance. I had problems that needed a solution. I was interested in getting into the specifics. Faced plenty of electronic faults and realized it was a black box for many. Since then I have attempted to understand each circuit I came across - mostly power supplies, welding inverters, valve driver, common appliance controls etc. Therefore, I like to understand design, just to understand how the circuit functions.Depending on how many years it has been since you took classes and how much practice you've had since then, you may have a lot of review ahead of you.

That being the case, my suggestion would be to force yourself to try to remember what you learned and only use the simulator for circuits that you can't analyze by yourself. Then use the simulation results to improve your understanding.
I switched to computers and software a few years after I graduated. I didn't design many circuits of my own for several decades. When I got back to it, I didn't have to do anywhere near as much review as I did for C, Perl, sed, csh, ... I'm not at the same level of competency as when I first graduated, but I don't need much of the underlying theory to do what I want to do.
I don't want to rain on your parade, but not being interested in what you were learning, only doing enough to pass tests, and never working with what you learned to help it sink in doesn't bode well for you recalling what you were taught.Never interested in the college lab and somehow managed to pass exams just for the sake of having the degree.
Yeah. I can't recall anything I've been taught but my profession helped me to learn some stuff and it helps me to be motivated to learn about electronics.I don't want to rain on your parade, but not being interested in what you were learning, only doing enough to pass tests, and never working with what you learned to help it sink in doesn't bode well for you recalling what you were taught.
I've known a number of people who got better grades than me in school, but many of them managed to do that without learning anything. When I was studying electronics, I was always on the dean's list for my grades, but that didn't mean as much to me as learning something that I could use to earn a decent living.
