Circuit fundamentals
Ohm's law, series and parallel networks, Kirchhoff's laws, source transformations, and systematic setup.
Electronics tutoring
A Socratic AI electronics tutor for understanding circuits
Circuit problems become easier when the schematic, assumptions, and equations agree. Draw or photograph the circuit, show your analysis, and let Stemio guide the next useful check.

What you can practice
Electronics work that stays connected to the reasoning
Because the tutor sees the diagram and calculations together, it can ask about a node, loop, polarity, or component model instead of giving generic circuit advice.
Dynamic circuits
Capacitors, inductors, RC/RL/RLC transients, time constants, impedance, and frequency response.
Analog electronics
Diodes, transistors, op-amps, biasing, gain, feedback, filters, and appropriate device models.
Signals and digital logic
Waveforms, basic signal processing, Boolean logic, gates, and connecting functional behavior to a circuit.
Guided problem solving
How a electronics session works
Draw or add the circuit and mark the quantities, directions, and reference nodes you chose.
Stemio checks the schematic against your equations and asks about the first mismatch or missing relationship.
As the analysis develops, recurring component or circuit concepts feed a focused study plan.
Problems you can bring
Start with the line where you are unsure
- Choosing node voltages for a multi-source network
- Checking an op-amp assumption before calculating gain
- Connecting an RC time constant to the expected waveform
Your level, your language
Guidance calibrated to the course you are taking
Use Stemio for introductory circuit analysis or more advanced electronics. The selected education level controls vocabulary and assumed background, not which supported circuit problem you may bring.
You can also choose your tutor language, so an unfamiliar term does not have to become an extra obstacle.
Common questions
About Stemio for electronics
Can Stemio read a hand-drawn circuit?
Yes. You can sketch the circuit on the whiteboard or add a photo, then label components and directions as you work through it.
Does Stemio support KCL and KVL?
Yes. It can help you inspect node and loop choices, polarity conventions, and the equations derived from Kirchhoff's laws.
Can it help with op-amps and transistors?
Yes. Analog components, filters, amplifiers, semiconductor basics, and digital logic are within the supported electronics scope.
