Inductors - An inductor is a passive electrical component used to store energy in a magnetic field.
Magnets - A magnet is simply any material capable of attracting iron
and producing a magnetic field outside itself, either naturally or
Resistors and Potentiometers - Resistors and potentiometers are passive electronic components that oppose the flow of either alternating current (AC) or direct current (DC).
Transformers - Transformers transfer electrical energy from one electric circuit to another, typically by the principles of electromagnetic induction. Transformer types include potential, current, step-up, step-down, distribution and others.
Transistors - Transistors are electronic devices made of semiconductor material that amplify a signal or open or close a circuit.
Vacuum Tubes - Vacuum tubes are electronic components used to amplify, switch, modify and/or create analog signals by controlling the movement of electrons in low-pressure spaces.
