Temperature Coefficient of Resistance

Temperature coefficient of resistance, this is the factor that temperature does affect the value of resistance in a resistor or a conducting wire. All the resistors value of resistance is specified at specific temperature and […]

Nifty NiMH Battery Charger

And now another interesting little project. After seeing numerous online projects I decided to build my own simple NiMH battery charger circuit using NiMH batteries because a bunch of GP2100 series NiMH cells are lying on […]

DHT11 Sensor Primer

In this guide we will learn how to play with a cheap ‘n’ cheerful temperature and humidity sensor DHT11 – the minuscule 4-pin sensor accurate enough for most do it yourself projects need to read […]

Voltage Divider and Current Divider

Voltage Divider and Current Divider are the most common rules applied in practical electronics. As you know, there are two types of combinations in a circuit, they are series and parallel connections. Parallel circuits are […]

What is an Electrical Circuit?

Electrical circuit is an interconnection of electrical components. An electrical circuit consists of batteries, resistors, inductors, capacitors, switches or transistors. An electrical network consists of a closed loop. A circuit is a closed path where […]

Types of Resistors

Resistors can be seen in almost all electronic circuits. There are many types of resistors and they can be divided into two groups namely fixed resistor and adjustable resistor (variable resistor). The main function of […]
