Introduction Working on electrical projects has taught me how essential every small component can be—especially a disc insulator. It is used in the overhead system, typically found between a conductor and a tower or pole, to stop the current from leaking into the earth. The insulating material of the device offers high resistance, which provides […]
Introduction In 1952, Jun-ichi Nishizawa designed a new type of diode that could handle weak light by using the photoelectric effect. This component, known today as the APD, helped move electrical systems forward, especially in early fiber-optic communication. His work with semiconductor diodes created a strong base for many modern applications. The APD uses a
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 When I first built a voltage amplifier, I was amazed at how a small input signal could increase in strength without affecting its shape. This electronic device plays a major role in audio tools and wireless communications, especially where signals need to be boosted. From that moment, I realized how the operation of amplifiers
The installation of the Electrical Breaker Panel wiring is no doubt complex, but not safe at the same time. Its major purpose is to distribute the electricity throughout the building, whether it is residential, commercial, or industrial. Well, the need for the installation can be due to a new circuit breaker or routine maintenance. So,

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 From my experience working in digital communication, I’ve seen how Adaptive Delta Modulation has become essential due to the growing demand for efficient analog-to-digital and digital-to-analog conversion. This technique improves traditional Delta modulation by changing the step size according to how the signal varies. It works especially well for low-frequency baseband signals, allowing them

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

Introduction In my early projects working with DC motors, I had to choose between brushless and brushed types depending on application needs. I noticed that brushless motors, also called BLDC, use electronic control instead of mechanical commutation, making them ideal where precise position and speed are needed. Brushed motors, with their brushes and coils, are
