The IC 555 timer was invented by “Signetic Corporation” and it was termed as SE or NE555 timer. Generally, it is a monolithic timing circuit that gives precise and highly stable delays of time or oscillation. These types of ICs are very cheap and reliable in cost when we compared with the OP-Amp applications in the same areas. These ICs are used as an astable and monostable multivibrators in digital logic probes, DC-DC converters, tachometers, analog frequency meters, voltage regulators, tem … [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 c … [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 t … [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...]
What is a Parallel Plate Capacitor : Working & Its Applications
In the digital electronic platform, we are so dependent upon mobile applications and devices for entertainment or work purposes. To make it handy, laptops or mobile phones come with rechargeable batteries. These batteries follow the phenomena of charging and discharging. Once charged these become mobile. All the rechargeable circuits possess capacitors in it. These capacitors are filled with various dielectrics results in different types of capacitors. For example paper capacitor, mica … [Read more...]
RVDT : Rotary Variable Differential Transformer
RVDT full form is a Rotary Variable Differential Transformer, which is used to measure the angular displacement of the test circuit. It plays a significant role in the field of aircraft (to measure the aircraft throttle and flap control systems), aerospace, medical field to measure or vary the angular displacement and stabilize the system. The operation principle is similar to that of LVDT, wherein the cam-shaped core rotates between the winding with the help of shaft. In this article, a brief … [Read more...]
