Capacitors consist of two metal plates separated by a layer of insulating material called a dielectric.
Capacitance is measured in units called farads (F). A farad is a very...
Transistors are solid state electronic switches. Solid state means that there are no moving parts, and the switching action is regulated by the arrangement of the semiconductor materials.

A resistive transducer is a device that senses a change to cause a change in resistance. Transducers do NOT generate electricity. Examples include:
Device

Where used
Light Dependent Resistor
Resistance falls with increasing light level
Light operated switches
Thermistor

Silicon Diodes and Zener Diodes
Diodes are one-way electrical valves that allow current to flow in one direction only.

Logic gates are at the heart of digital electronics. In digital electronics, we need to know nothing about electricity, other than the difference between on (1) and off (0).
