Generally, Power plants require steam for the purpose of heating. Hence, this purpose is fulfilled by the boiler, where the steam is produced by boiling water. Basically, the steam is produced by boiling water beyond its boiling point where it changes its state from liquid to vapor and this vapor is known as steam. So, […]

Four Point Starter Working and Applications
A device that gives the motor some initiation to start safely is termed as a Starter. While starting a motor, it draws huge current from the line which damages the internal parts of the motor. Four-point starter helps in limiting the starting current such that the motor begins to attain speed slowly and runs smoothly. […]
Three Point Starter – Construction, Working, Drawbacks and Applications
A device that gives the motor some initiation to start safely is known as Starter. Similarly, the three-point starter is common for the starting purpose which is used to start DC compound or shunt motors. While starting DC shunt motor it draws huge current from the line which damages the internal parts of the motor. […]
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 […]
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 […]
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 […]
Common Emitter Amplifier and Transistor Amplifiers
We generally use various types of electronic devices to design electronics projects or circuits. In some circuits or projects the output signals will be having low strength and are required to be amplified, to detect or use the output. Thus, the output signal can be amplified using amplifier circuits such as single stage transistor amplifiers, […]
Biosensors – Types, How Does it Work and Applications
The Biosensor is used to detect the analyte so the Biosensor is an analytical device and it gathers the biological components with a Physicochemical detector. The sensing biological elements are biometric components interact with the recognize and analyze the study and the components like tissue, microorganisms, antibodies, nucleic acids and etc. The sensitive elements of […]
