Topic 10 RC Networks with DC
RC Network At its simplest the RC network is a series circuit consisting of a capacitor and a resistor connected to a...
Topic 9 Capacitors
Capacitors consist of two metal plates separated by a layer of insulating material called a dielectric. Capacitance is measured in units called farads (F)....
Topic 8 Operational Amplifiers
The operational amplifier was originally developed for analogue computing (our PCs are digital computers) and when introduced were complex and expensive components. ...
Topic 6 Transistors and MOSFETs
Transistors are solid state electronic switches. Solid state means that there are no moving parts, and the switching action is regulated by the arrangement...
Topic 5 Resistive Input Transducers
A resistive transducer is a device that senses a change to cause a change in resistance. Transducers do NOT generate electricity. Examples include: Device Action Where used Light Dependent Resistor...
Topic 4 Diodes
Silicon Diodes and Zener Diodes Diodes are one-way electrical valves that allow current to flow in one direction only. Click HERE to...
Topic 3 Basic Electricity
Grounding In many circuits, a zero reference point is shown connected to earth, or grounded. In this circuit, the point Y has been connected to ground, and...
Topic 2 Logic Gates and Boolean Algebra
Logic gates are at the heart of digital electronics. In digital electronics, we need to know nothing about electricity, other than the...
