In the works
Electrical engineering
Circuits, the electromagnetic field and the basics of electronics. The tutor hands calculations to machine checking and tells you whether they hold.
Planned topics
We're still preparing lessons for this subject. Below are the topics we're planning; they aren't in the app yet.
Electric circuits
Kirchhoff's laws and circuit analysis.
Alternating current
Phasors, impedance and resonance.
Electromagnetic field
Maxwell's equations and electromagnetic waves.
Capacitors and inductors
Transients and RLC circuits.
Basics of electronics
Semiconductors, diodes and transistors.
Key formulas
Concept
Formula
Ohm's law
U = I · R
Kirchhoff's current law
Σ Iᵢₙ = Σ Iₒᵤₜ
Capacitive impedance
Z_C = 1 / (jωC)
Don't let Kirchhoff beat you.
Electrical engineering lessons are still in the works. Create an account and start with thermodynamics, which is already available.
