For the functioning of many electronic circuits, filters hold the most importance. So, people in the domain of electric and electronics, show interest in the development of filters. In general, a filter is termed as the electric network which modifies either the amplitude of phases of the signal corresponding to the frequency. And then the active filter is the analog circuit which is designed using active components usually amplifier. And these active … [Read more...]
What is Ceramic Capacitor : Construction & Its Working
The word capacitor comes from ‘capacity’ and a capacitor has the capacity to store electrical power. Capacitors are an integral part of electrical circuitry, in power circuits, their role as power factor improver and power storage device cannot be underemphasized. After batteries, the capacitor is the only device that can store electrical power. Capacitors are also used as power quality improver. However, in electronic circuitry, capacitors have many more … [Read more...]
Difference between Resistance and Resistivity
In the electrical and electronics industries, the concepts of resistance and resistivity are the most important ones. One has to be clear regarding why these topics hold prominence and what are differences and comparisons? The foremost difference is that resistance opposes the electron flow, while resistivity defines the material’s resistance having the corresponding dimension. So, here is a detailed view of all these topics. This article discusses an … [Read more...]
Differences between DC Series and Shunt Motors
Before knowing about the differences between DC Series and Shunt Motors, let us start to know what a DC motor is. An electric motor that is powered up by direct current is termed as DC motor. In a detailed view, when a current-carrying conductor is positioned in the area of a certain magnetic field, it gains some torque and tends to have a moment. So, this is the same principle where a DC motor also works on. A DC motor is also named depending on the type … [Read more...]
What is an Ohmmeter : Working Principle & Its Types
Initially, ohmmeters were evolved based on the design construction of a meter known as “Ratiometer”. Ohmmeters under this classification only calculate the value of resistance because they are not simply integrated into the multimeter construction. Insulation testers which depended on a hand moved generator also works on a similar operation. This makes sure that indication was completely autonomous of the developed voltage. Following this, various designs … [Read more...]
What are Digital Sensors : Types and Their Uses
Electrochemical and electrical sensors are usually one part of the measuring sequence. And this sequence generally comprises of a sensor, transmitter, and a cable. And the foremost classification of sensors is analog and digital. The digital sensor technology is more substantial in regard to its extensive reliability and exactness. Digital sensors are the contemporary replacements of analog sensors because of few drawbacks in the analog type of sensors. … [Read more...]
What are Analog Sensors : Types and Their Characteristics
As we all are living in digital technology, the one device that became an integral part of our daily activity is Sensor. Every device which we come across in our home from mobile phone to security systems at home, all are embedded with various kind of sensors. So, a sensor is a device that observes changes occurring in the parameters such as humidity, pressure, temperature, and others and sends the output to either microcontroller or microprocessor. And … [Read more...]
What is Peristaltic Pump : Working Principle & Its Applications
A peristaltic pump is one of the most frequently used pumps for transferring liquids from one point to another. Mostly it is used in medical applications and laboratory applications. In medical applications like dialysis, it proves very useful to transfer blood from one part to another part. The best thing in this pump is the liquid to be transferred does not comes in contact with the pump. It remains in the pipe which is used to carry or transfer the … [Read more...]
What is a Variable Resistor : Working Principle & Its Applications
The variable resistor is an element that offers variable resistance to the circuit. By adjusting its internal configuration, we can obtain variable resistance at the load side. This element is frequently used in electrical and electronic circuits to vary the current flowing in the circuit. Apart from varying current, this element is also used to control some basic parameters like speed, temperature for commonly used electrical loads. A simple example would … [Read more...]
What is a Steam Turbine : Working, Types & Its Applications
Steam turbines are available from the past 100 years and these are manufactured and used in different plants like the combined cycle, fossil power, nuclear plants. The first steam turbine was designed in the year 1884 by Sir Charles A. Parsons. This turbine was simply generated 7.5 KW of energy and used in Newcastle, England for lighting an exhibition. At present, steam turbines can generate above 1,000 MW of energy which is used in major power plants. The … [Read more...]
