How A Darlington Pair Transistor Works
A Darlington pair is two transistors that act as a single transistor but with a much higher current gain, this tutorial provides an example circuit with explanation about how the part is used.
How A Transistor Works
A transistor in its simplest form is an electronic switch. This tutorial explains how a small amount of current can be used to switch on or off a much larger amount of current.
How Colour Changing LEDs Work
A colour changing LED contains a red, green and blue LED along with a small computer to drive them, but how do they work to produce different coloured light? Find out in this tutorial.
How To Calculate Capacitors In Series And Parallel
Calculate the combined total capacitance of capacitors in parallel and series using the formula and explanations detailed in this tutorial. As well as explaining the formulas and maths involved there is also some tasks for you to test yourself for two and three capacitor networks.
Understanding Ceramic Disc Capacitor Values
Ceramic disc capacitors markings are a two or three digit value, this tutorial explains how to use the code to determine the capacitance in Farads.
How To Use Capacitors
A guide on using capacitors, their circuit symbol, values & charging through a resistor.
How to Calculate Resistors in Series and Parallel
Calculate the combined resistance of resistors in series or in parallel using the formulas and explanations described in this tutorial. As well as explaining the formulas and maths involved there is also some tasks for you to test yourself for two and three resistor networks.
How To Calculate And Understand Resistor Values
The value of a resistor can be calculated using the colour bands on the resistors casing, find out what each colour means and how to read them with this tutorial. Resistor tolerances, a worked example, the resistor preferred value system and some tasks for you to try are also included.
How an LDR (Light Dependent Resistor) Works
A light dependant resistor or LDR is a sensor that changes resistance as the light level changes, see example circuits and explanations in this tutorial. This tutorial also covers what an LDR looks like, the circuit symbol, typical resistances for different light levels and some example applications.
Understanding Component Uses & Symbols
Learn about resistors, capacitors, diodes & transistors. In this guide find out what they do, how they work and what the circuit symbol is to represent them.
