In this project, we will make a CD4047 Inverter Circuit, and we will also discuss why this type of inverter is not a good or reliable solution for real-world applications. An inverter is an electronic device that converts DC voltage into AC voltage. Inverters play a very important role in power backup systems, especially in […]

Hall Effect Transducer Construction, Working and Applications
A Hall effect transducer is a sensor that detects a magnetic field and converts it into a proportional electrical signal using the Hall effect phenomenon. It is widely used for current sensing, position sensing, speed detection, proximity sensing, and magnetic field measurement in industrial, automotive, and consumer electronic systems. Unlike conventional mechanical or contact-based sensors, […]
TVS Diode: Symbol, Construction, Working, Types and Applications
A TVS (Transient Voltage Suppression) diode is a specialized semiconductor device used to protect electronic circuits from high-voltage transients such as electrostatic discharge (ESD), lightning surges, and switching spikes. It responds extremely fast and clamps overvoltage to a safe level before they damage sensitive components. Modern electronic systems are highly sensitive to voltage spikes caused […]
Light Emitting Diode LED – Symbol, Construction, Working, Types and Applications
The Light Emitting Diode (LED) is one of the most widely used electronic components today, found in everything from indicator lights to full-scale lighting systems. It is a type of diode that converts electrical energy into light energy, offering a highly efficient alternative to traditional bulbs. Unlike incandescent lamps that rely on heating a filament, […]
Laser Diode – Symbol, Construction, Working, Types and Applications
A laser diode is a semiconductor device that emits coherent light through the process of stimulated emission. It operates similarly to a light-emitting diode (LED) but produces a focused, monochromatic, and coherent beam of light. The emitted light waves have the same wavelength, frequency, and phase. The laser diode was invented by Theodore H. Maiman, […]
UJT Unijunction Transistor Symbol, Construction, Working & Applications
The Unijunction Transistor (UJT) is a three-terminal semiconductor device that is mainly used for triggering, pulse generation, relaxation oscillators, and phase control circuits. Unlike the Bipolar Junction Transistor (BJT) or Field Effect Transistor (FET), the UJT does not function as an amplifier; instead, it acts as a switching device with negative resistance characteristics. The UJT […]
