A high pass filter allows high-frequency signals to pass through while blocking lower frequencies. It is widely used in audio processing, electronics, to reach the cleanness of sound, eradicate noise and to accent particular details, making it critical to obtain clean sound.   Have you ever been writing a transcript for a particular podcast and … Read more

An open-loop control system works without feedback, like a fan running at a fixed speed. In contrast, a closed-loop system adjusts automatically using feedback, like an air conditioner maintaining room temperature. Closed loops are smarter and more efficient.   Ever wondered why some devices work perfectly without you adjusting them? That’s the magic of closed-loop … Read more

The Nyquist plot builds on polar plots to check the stability of closed-loop control systems by changing ω from −∞ to ∞. It shows the full frequency response of the open-loop transfer system. The Nyquist plot is a useful tool in control systems and signal processing for studying a system’s stability and frequency response. In … Read more

Electric poles are essential for delivering electricity to homes and businesses. They carry power lines high above the ground, ensuring safe and reliable connections. Understanding how these poles work helps us appreciate their role in powering our daily lives.   We know that wires insulate electric poles and we also feel that these poles are … Read more

A circuit breaker is a device that stops the flow of electricity to prevent too much current from flowing due to a short circuit or overload. Its main job is to stop the current when there is a problem. A vacuum circuit breaker uses a vacuum to extinguish the arc. Vacuum interrupter technology first appeared … Read more

Air circuit breaker is an electrical device that controls and protects circuits. It can break a circuit manually or remotely during normal conditions and shuts it off in case of faults like short circuits or overcurrents. Circuit breakers often work alongside devices like relays, switches, and fuses to ensure safety. They are widely used in … Read more

An Ideal Transformer is a type of electrical  device that perfectly transfers  the energy between two circuits without any power loss. It efficiently changes voltage levels, making electricity safer and more usable for homes, businesses, and industries.   Imagine a device that transfers energy perfectly, without wasting any power. That’s the beauty of an ideal … Read more
