Introduction In the world of electricity, disc-shaped insulators act as silent guardians, keeping the current separated from what could be shocking. Like stones in a river, these champions manage transmission and distribution across lines, systems, and landscapes, working tirelessly to maintain safety. Their role ensures that lights keep buzzing, appliances stay humming, and every neighborhood
Introduction The avalanche photodiode (APD) is a highly responsive semiconductor device that converts light into electric signals using the photoelectric effect. First designed in 1952 by the Japanese engineer Jun-ichi Nishizawa, the APD has become a key component in various applications, especially in fiber-optic communication systems. In recent years, graphene layers have been added to

Introduction When working with electric systems in large industries, I’ve often seen how vital circuit breakers are in ensuring safety. Whether operated manually or remotely, their function is to break the circuit under abnormal conditions like overcurrent or short circuit faults. One key type I’ve worked with is the air circuit breaker, commonly used for
Introduction A voltage amplifier is an electronic device that takes an input signal and improves its strength without changing the shape. It can handle small or large signal sizes depending on the function and configuration, and this article provides a brief look at how it depends on the relationship between supply, load, and current. Such
Introduction Wiring a circuit breaker panel correctly is an important task to ensure home safety and the efficient distribution of electricity. Whether you’re a DIY enthusiast or a professional electrician, following the right wiring techniques and key steps is essential for a successful wiring project. Performing this task with a careful approach can help avoid

Introduction My first encounter with USM was during a lab session where I tested ultrasonic motors that didn’t rely on electromagnetic fields, unlike conventional ones. These motors are utilized in a completely different way—they depend on the piezoelectric effect and produce vibrations at ultrasonic frequencies, specifically from 20 kHz to 10 MHz, which humans can’t
Introduction In modern communication systems, the need to transmit signals across long distances has led to advancements in technology and an increase in demand for efficient methods. The properties of a high-frequency signal, such as amplitude and phase, can be changed during the process of modulation to match a low-frequency baseband signal. Over time, digital
Introduction From my hands-on experience working with electric motors, I’ve seen how vital a starter is to protect them from overload and short circuits. A 2 point starter is one of the simplest types of starters, often used where basic protection and control are enough. Unlike 3-point or 4-point designs, this type skips the No
Having worked on electrical setups in both homes and offices, I’ve seen how a constantly tripping breaker is more than just an inconvenience. It’s a warning signal — your circuit is crying out about an underlying issue in the system. If ignored, this problem can quickly turn hazardous, creating serious safety risks. Each trip can
