Vol. IV — Electronics · Trainer
A closed loop, Ohm's law, series and parallel, then capacitors, RC time, Kirchhoff, Thévenin, Norton, Superposition, diode I-V, mesh/nodal equations, BJT common-emitter bias, and an N-channel MOSFET as a voltage valve. Change the knobs. The numbers and the drawing update together.
Current only moves when the path is complete. Open the switch, then close it. Watch the loop light up.
I = 0 while the switch is open.
