What is Diode Approximations : Types & Its Problem

April 23, 2020 By WatElectronics

Diode

Diode Approximations are how the Diodes present in the circuit gets analyzed. The diode can be considered as the basic electronic device in any type of circuit. These are of various types a design criterion is based on the requirement. The analysis of it can be done based on the Three approximations. Each approximation can be done by considering the diode as a switching element. For these basic components called Diodes, there exist three approximations. In each one, the initial and the … [Read more...]

What is Megger : Construction, Working and Its Applications

April 21, 2020 By WatElectronics

Megger

It is quite easy to measure the resistance of a resistor. However, measuring the resistance of an insulator can be a difficult task. This is because the resistance of insulators is extremely high. For that, a device called megger is used which can be used to measure the relatively high value of resistance of insulators. The resistance is measured by comparing the unknown resistance of the insulator to that of the known value of resistance of a material. The circuit comprises two voltage coils … [Read more...]

What is Resistance Thermometer : Construction & Its Working

April 20, 2020 By WatElectronics

Resistance Thermometer

A Thermometer is a device that is used in the measurement of temperature. A resistance thermometer is a type of thermometer which can be used to give extremely accurate results. The temperature is measured by measuring the change in resistance. The thermometer consists of a platinum wire placed inside glass probes. The device is evacuated to prevent an unnecessary rise in temperature. The device is extremely fragile and hence kept within protective probes. They have extremely high accuracy and … [Read more...]

Difference between LVDT and RVDT and Its Advantages

March 27, 2020 By WatElectronics

LVDT&RVDT

Linear Variable Differential Transformer (LVDT) and rotary variable differential transformer (RVDT) is an electrical transformer type sensor used to measure the linear displacement and angular displacement respectively. The circuit diagram and working principle is similar to each other but differentiated in terms of core and shaft movements inside the module. These sensors are also called as electromechanical transducer due to the fact that it yields variable alternating current (AC) output … [Read more...]

What is Half Subtractor : Working and Its Applications, K-MAP, Circuit using NAND Gate

March 2, 2020 By WatElectronics

half-subtractor-block-diagram

To process the information like light or sound from one point to other we can use analog circuits by giving proper inputs in the form of analog signals. In this process, there are chances of noise being picked up by the input analog signals and this may lead to loss in the output signal, it means whatever the input we are processing at the input level is not equal to the output stage. To, overcome these digital circuits are implemented. Digital circuit can be designed with logic gates. Logic … [Read more...]

Sum of Products and Product of Sums : Types and Schematic Diagrams

February 29, 2020 By WatElectronics

Basic K-Map

We are all more familiar with the terms SUM and PRODUCT in mathematics. Based on these terms, AND and OR logical operations are derived. Any kind of logical expression can be represented through these terms and there are many ways of expressing a logical function. AND represents the product relationship between the terms whereas OR represents sum relationship. So, Sum of Products and Product of Sums are the equivalent approaches of representing a logical expression. Through few principles, these … [Read more...]

What is a Bypass Capacitor : Types, Functions & Its Applications

February 25, 2020 By WatElectronics

Bypass-Capacitor

A capacitor is a device that can be used to store electric energy. It has two terminals and its effect is called capacitance. A capacitor basically consists of two metal plates that act as a conductor with a dielectric medium in between. The conductor may be in the form of electrodes or metal plates or thin foil. The dielectric material is used to increase the capacitance. There are different types of capacitors and a bypass capacitor is one of them. It is a component in an electric circuit that … [Read more...]

What is a Surge Protector: Working, Types, Advantages & Disadvantages

February 23, 2020 By WatElectronics

Surge Protector

There are various types of electronic devices used in our day to day activities. Many of these appliances require a power supply as the basic unit for functioning. This supply provided at home or for the business purpose is not constant as there would a lot of surge. The generation of the surge is due to the thunder striking or it may be because of the type of electromagnetic noise generated or may also be due to grid switching.  To protect the appliances from such voltage spikes protection is … [Read more...]
