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 reference of known temperature. Whenever the junction is experiencing a change or alteration in temperature, a difference in voltage is created … [Read more...]

What is a Thermocouple : Working, Diagram and Its 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 to an entity whose temperature is already known. The unknown temperature junction is known as the measuring or hot junction while the known temperature … [Read more...]
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 to derivation being not done perfectly well. So, 100% measurement error is not possible with any methods. It is very … [Read more...]
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 transformer rating.Most of the batteries require a high current output produced by high power type Transformer Bridge … [Read more...]
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 Capacitor consists of two electrode plates which are separated by an insulating or … [Read more...]
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, multistage transistor amplifiers, common emitter amplifier, and so on. But, what is amplifier circuit? … [Read more...]
