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 […]
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 […]
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 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 […]
Conductance, Temperature coefficient, resistivity and specific resistance are the properties of an electric conductor or any other material. They all can be understood by resistance. Resistance is the amount of obstruction in the flow of […]
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 […]
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 […]
A source is a device which converts mechanical, chemical, thermal or some other form of energy to electrical energy. The types of sources available in the electrical network are the voltage source and the current […]
The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. A conductor has free electrons randomly moving inside. When an electric potential is applied to it, the electrons collide […]
Current is the measure of the rate of flow of electric charges across the conductor. It is measured in the unit of Ampere. This current measurement in a circuit is mostly done by Ammeter. Ammeter […]
