What is RC Phase Shift Oscillator : Circuit Diagram & Its Working

October 29, 2020 By WatElectronics

RC Phase Shift Oscillator

An oscillator is a mechanical or electrical construction that produces oscillation based on some variables. This oscillator is used from clock to various metal detectors and even on computers where microprocessors and microcontrollers exist The oscillator in which the RC circuit is used as a feedback path is the RC phase shift oscillator. It generates stable sine waves that are used in low-frequency generations, particularly in the audio frequency range. The amplifier provides a phase shift of … [Read more...]

What is Band Pass Filter : Circuit & Its Working

October 26, 2020 By WatElectronics

BPF - Band Pass Filter

During signal processing, a device called a Band Pass Filter or BPF is needed to allow a particular range of required frequencies and to avoid unwanted frequency ranges or components. By this filtering noise signal can be reduced by eliminating frequencies that are not required. Different types of filters like linear and nonlinear, analog, digital, active and passive, etc. are available to use based on the requirement. This article discusses an overview of Band Pass Filter. What is Band Pass … [Read more...]

What is an Inductive Reactance : Formula & Its Working

October 1, 2020 By WatElectronics

Inductive Reactance

An inductor is normally a coil of wire. When current is passing through that coil, the electric field will be generated. So the field will get induced. The induced filed depends on the number of turns and this is inductance. An inductor due to its inductance resists the flow of alternating current. Basing on the Lenz's law inductor will resist change in current. Reactance is defined as the resistance offered to the AC currents by capacitors and inductors only. Usually, reactance is denoted by X, … [Read more...]

What is an Open Loop Control System & Its Working

September 30, 2020 By WatElectronics

Control System

The collection of subsystems that controls the input signal to get the desired output is known as a system. The main function of any electronic system is regulating the output and keep that within systems desired input i.e when the input of the system changes, the output of the system should respond and change according to the changed input value. In another case, if there is no change in input but the output of the system is getting disturbed then the output should respond by coming back to its … [Read more...]

What is an ACSR Conductor & Its Working

September 30, 2020 By WatElectronics

ACSR Conductor

A physical medium that carries electrical energy from one place to another place is known as a conductor. The minimum conductivity and tensile strength are important factors for transmission and distribution systems. In the earlier days, the copper conductors have used to transmit the energy. But now, these are replaced with stranded hard-drawn 1350 aluminum wires to increase the tensile strength, conductivity, and efficiency. The aluminum conductors are lightweight, economical in design, and … [Read more...]

What is Arduino Sensor : Types, Working and Applications

September 22, 2020 By WatElectronics

Arduino Sensor

An electronic device that senses and responds quickly to physical changes such as distance, pressure, temperature, touch can be referred to as sensors. These are used commercially in various products for temperature monitoring, alarming circuits, and in the Home automation kits, etc... In the practical world, where the motive is to design a user-friendly environment such that various devices information can be controlled, sent, and monitored. This is made possible when the multiple sensors are … [Read more...]

What is Carbon Composition Resistor & Its Working

September 8, 2020 By WatElectronics

Carbon Composition Resistor

In electronic circuits, resistors are the passive two-terminal devices used to regulate or reduce the flow of current in the circuit. Mostly fixed type resistors are used in the electronic circuits because of its fixed resistance value. The resistance is determined during the manufacturing process itself and it can't be varied like a variable type resistor. Based on the manufacturing process, the fixed type resistors are divided into 4 types such as carbon resistors, wire wound resistors, … [Read more...]

What is an Anemometer : Working & Its Applications

August 20, 2020 By WatElectronics

Anemometer

The first mechanical anemometer is invented by Leon Battista Alberti, who was an Italian artist and an architect in the year 1450. Later on, many changes are made and invented different types of anemometers to measure wind speed and pressure more accurately. The design and its working principle didn't change over hundreds of years. It is a meteorological device that can estimate whether conditions. These are used in many applications like monitoring the weather conditions, measure the air … [Read more...]

What is Metal Oxide Varistor & Its Working

August 18, 2020 By WatElectronics

Metal Oxide Varistor - MOV

A passive two-terminal semiconductor device that is used to protect electronic and electrical circuits is called Varistor. It protects against over-voltage by clamping of voltage. It is also known as a voltage dependant resistor (VDR) or non-linear resistor. The resistance of the varistor is changed due to the change in voltage across it. The varistors are non-ohmic variable resistors with symmetrical current and voltage features applicable for both DC and AC applications. In AC operations, … [Read more...]

What is a Bolometer : Working & Its Applications

August 17, 2020 By WatElectronics

Bolometer

In 1878, Samuel Pierpont Langley, an American astronomer invented a sensitive instrument to detect heat and electromagnetic radiation. This instrument is called a Bolometer which is used to measure the low and medium power of microwave energy. In the 1880s, Langley's Bolometer was invented for the detection of thermal radiation. It can measure the power of electromagnetic radiation by using heating material and temperature resistive element. The Bolometers are very sensitive, efficient, better … [Read more...]
