Circuit Simulation
Online LTspice Tutor for Circuit Simulation
LTspice is a free, fast SPICE simulator used in many circuits and electronics courses. Drawing the schematic is usually the easy part; knowing which analysis to run, how to set it up, and whether the result makes sense is where students get stuck.
Sessions cover the tool and the circuit together, so a simulation becomes a way to check and understand your analysis rather than a black box.
Topics
What we can help with
Common areas students ask about when working with LTspice.
Building the circuit
- Schematic entry
- Components and component values
- Voltage and current sources
- Ground, labels and net names
Running analyses
- Simulation commands
- DC operating point
- DC sweep
- AC analysis
- Transient analysis
Reading results
- Waveform viewer
- Measurements and .meas
- Parameter sweeps with .step
- Interpreting results against theory
Models and troubleshooting
- Basic model usage
- Simulation errors and convergence problems
- Results that look wrong
These are common areas rather than a complete list. Specialist semiconductor models and advanced features vary, so send us the details of your circuit and we will tell you how we can help.
Two ways to use sessions
Learning LTspice, or using it in your course
Both are common, and most sessions combine them in whatever balance you need.
Learning LTspice itself
Learning LTspice itself: drawing clean schematics, choosing and configuring analyses, and reading waveforms and measurements correctly.
Using LTspice in your coursework
Using LTspice for your course: checking a hand-calculated circuit, simulating a filter or amplifier for a lab, or finding out why a simulation disagrees with theory.

What students simulate in LTspice
LTspice supports circuits and electronics courses in particular:
Circuit analysis
Confirming nodal and mesh results, operating points and Thevenin equivalents.
RC, RL and RLC circuits
Watching transient responses and resonance, and checking time constants against calculation.
Filters
Plotting frequency responses and cutoff frequencies with AC analysis.
Amplifiers
Checking transistor bias points, gain and bandwidth, and op-amp circuit behaviour.
Power circuits
Simulating rectifiers and simple converters where they are part of your course.
Who this tutoring is for
- Students taking circuit analysis or electronics courses
- Students using LTspice for labs and pre-lab simulations
- Students whose simulation will not run or disagrees with their calculations
- Students new to circuit simulation who want a clear start
How online sessions work
Live 1-to-1 sessions on Zoom or a similar platform, with screen sharing and a shared digital whiteboard. For LTspice, sessions typically include:
- Screen sharing on your own LTspice installation
- Schematics built and checked together
- Each analysis chosen for a reason, then set up step by step
- Simulated results compared with hand calculations

FAQ
LTspice tutoring questions
Which LTspice analyses can you help with?
DC operating point, DC sweep, AC and transient analysis are the most common, along with parameter sweeps and measurements.
My LTspice simulation doesn't match my calculations. Can you help?
Yes. Sessions check both the simulation setup and the hand analysis to find where they differ — which often teaches the most about the circuit.
Can you help with LTspice convergence errors?
Yes. Convergence problems usually come from floating nodes, unrealistic component values or unsuitable settings, and sessions work through how to find and fix them.
Do you support other circuit simulators?
Yes, other simulators such as PSpice, Multisim and Proteus can be requested too. Tell us which one your course uses.
