What Is An Intergrated Circuit?

What is an Intergrated Circuit? Who invented the Integrated Circuit? What are some examples of Integrated Circuits? How are they made?

What Is Ohm’s Law

Ohm’s law is used to describe the relationship between Voltage (V), Current (I) and Resistance (R). In this tutorial you will learn about the formula that connects these three values, see some examples and answer some questions to test your understanding.

How A Thermistor Works

A guide to understanding how a thermistor works. A thermistor is a component that has a resistance that changes with temperature. There are two types of thermistor. Those with a resistance that increase with temperature (Positive Temperature Coefficient – PTC) and those with a resistance that falls with temperature (Negative Temperature Coefficient – NTC).

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.
