Electrical isolator which is commonly known as isolator or disconnector is a piece of equipment that is used in electric devices and power systems with the main function of effectively isolating two different parts of an instrument. By definition, isolation is the process of complete separation of various parts of an apparatus and this separation […]
Types of Thermocouples with Temperature Ranges & Color Codes
Thermocouple can be defined as a sensor or device which is used for sensing or measuring temperature. The thermocouples are consisting of two metals or wires and the metals are known as legs. Both legs are welded together so as to create two junctions. Temperature is measured in these junctions with the help of a […]
What is a Thermocouple? Definition, Working Principle, Diagram & Applications
To know about what is a thermocouple we have to know of its definition. Thermocouple can be defined as a device comprising of at least 2 joined metals which forms 2 junctions. One of the junction is connected to the body of the device whose temperature is required to be measured, while second is connected […]
Electronic Light Dimmer Circuit using TRIAC
The light sources such as tube light or bulbs blink according to their particular watt rating. If you need more light, then you have to use high watt bulb and if you need low light, then you have to replace with low watt rating bulb. But, if there is not needed to change the brightness […]
Different Types of Errors in Measurement and Measurement Error Calculation
The measurement of an amount is based on some international standards which are completely accurate compared with others. Generally, measurement of any quantity is done by comparing it with derived standards with which they are not completely accurate. Thus, the errors in measurement are not only due to error in methods, but are also due […]

Temperature control is a procedure to maintain the temperature at a certain level. This method is commonly used in all regions of the world. Recently in the globalization period, this method becomes an important part because there are several applications in daily life includes this procedure especially server room and greenhouse. Every day server room […]
SCADA Applications in Power System
Supervisory control and data acquisition (SCADA) is an industrial control system which is used in many modern industries like energy, manufacturing, power, water transportation, etc. SCADA systems organize multiple technologies that allows to process, gather and monitor data at the same time to send instructions to those points that transmit data. In today’s world, almost […]
How to Make a Rechargeable Super Capacitor Battery
Battery Charger is an electronic device that can be used to re-energize a “Secondary Cell” or a “Rechargeable Battery” using a power supply source. Generally battery chargers can be consider as “DC Power Supply Source”, step-up/down transformers will be used to regulate the voltage of AC mains input, to the required levels based on the […]
What is Polyester Capacitor? Number Coding & Colour Coding
As a widely used electrical component capacitor plays an active role in the functioning of any circuit and without it the circuit design will not be completed. It is an important and useful component because it has features like energy storing capability, minimizing sudden voltage changes, selectivity of frequencies, bypassing of frequencies, phase shifting, etc. The […]
What is a Varactor Diode? Working and Characteristics
In general, we frequently use multiple number of electronics and electrical components to design electronic circuits. These basic components include resistors, capacitors, diodes, transistors, integrated circuits, thyristors, transformers, and so on. Let us consider diode which is a two-terminal semiconductor solid state electronic device. Diode exhibits nonlinear V-I characteristics and it allows the current to […]
