We all know that an operational amplifier is the analog type of circuit that considers differential voltage as input and provides a single-ended voltage as output. These op-amps are mainly employed in the voltage follower circuits. But the arrangement of the op-amp in the voltage follower imposes high risk and capacitive stacking of oscillations. These huge loads show more impact on the operational amplifier stability dependent applications. So, let us know how the arrangement can be done in a … [Read more...]
What is Gate Turnoff Thyristor & Its Working
"Thyristor" is a semiconductor device that is popularly used as a switch in power circuits. With alternating layers of P-type and N-type materials, the thyristor is designed as a four-layered structure. It is available as both two-lead and three-lead designs. The three-lead design of the thyristor consists of an anode, a cathode, and a Gate lead. The thyristor usually starts conducting when the gate lead is triggered with the current and once turned ON, the thyristor conducts continuously until … [Read more...]
What is Shunt Capacitor : Working & Its Advantages
Capacitors' invention was initiated in the beginning days of electricity. In the initial days of development, capacitors were called condensers. This term was primarily utilized for the objective of high-power applications by Alessandro Volta in the year 1782. Thereafter, the term condenser was not in usage because of the complicated meaning of steam condenser and replaced by the name ‘capacitor’ in the year 1926. Now, this article provides a clear analysis of one foremost type of capacitor … [Read more...]
What is Filter Capacitor : Working & Its Applications
The Filter Capacitor is a basic type of capacitor. It is designed in such a way that, it can prevent a certain range of frequency signals to enter another circuit. It is mostly preferred during the filtering of the low-frequency signals. A capacitor is generally used as a parallel plate capacitor. In this case, the capacitor is connected to the respective circuit so that the desired signals are filtered and excess signals are eliminated from the circuit. This type of capacitor has many … [Read more...]
What is 7805 Voltage Regulator & Its Working
When there are fluctuations in the circuit, then the fixed output cannot be given by all voltage sources. To deal with this, a system is designed to maintain a constant voltage level automatically is Voltage Regulator. These voltage regulators are used in computer power supplies for stabilizing the DC voltages. Coming to power station generation plants and automobile alternators, the output is controlled by these voltage regulators. The regulation of one or more AC or DC voltages is done … [Read more...]
What is Carbon Composition Resistor & Its Working
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 RGB LED : Circuit & Its Working
The term LED stands for Light Emitting Diode. In electronic circuits, the LED is a type of PN-junction semiconductor diode, which can emit light when current flows through the circuit in the forward direction. This indicates whether the electronic device is working or not. LEDs are widely used in various applications such as in cars, bikes, home appliances, offices, lighting, mobiles, televisions, etc. Usage of Multi-colored LEDs in the device reduces, cost, power and emits more than one colored … [Read more...]
What is a Varactor Diode : Working & Applications
In the digital electronic circuits, one of the basic essential devices is diodes. A diode consists of two terminals. These two terminals connected to the supply results in conduction. The way the terminal sare connected makes it classified as a forward-biased diode or reverse-biased diode. In forward bias, the diode allows the current to flow through it. During reverse bias, it blocks the flow of current. This reverse biasing is used in the case of the varactor diode. Based on the … [Read more...]
What is a Rheostat : Working & Its Applications
In an electric circuit many times it is desirable to restrict the current, which can either be done by reducing the voltage or increasing the resistance in the circuit (Ohm’s Law). A rheostat is a device that facilitates this. The word rheostat is derived from the Greek language meaning changing stream (current). It is a must for any electrical laboratory/workshop in order to carry out experiments under variable current and voltage conditions. This is done by inserting a variable resistance in … [Read more...]
What is a Gyroscope Sensor : Working & Its Applications
MEMS or Microelectromechanical systems are basically microsystems that have a very small size. It is an extremely advanced form of technology that has given rise to different electronic components like accelerometer and gyroscope sensor. An accelerometer is a device that can be used to detect non-gravitational motion. A gyroscope sensor, on the other hand, can be used to detect gravitational motion. Thus, we can see that a gyroscope sensor and an accelerometer complement each other. Both of … [Read more...]
