Overhead transmission lines are an integral part of the electrical grid system. They are used to transfer electricity from one location to another and can be seen running along roads, highways, and sometimes over bodies of water. Overhead transmission lines have been around for more than a century, with the first built in 1882 by… Read More

A solenoid is a coil of wire that creates a magnetic field when an electric current is passed through it. The term “solenoid” comes from the Greek word for “pipe,” because early solenoids were simply coils of wire wrapped around a pipe. Solenoids are used in many devices, including door locks, car starters, and electromagnets.… Read More

Electric current is the rate of flow of electric charge. The SI Unit of electric current is the Ampere, which is equal to a flow of one coulomb per second. Electric current can be either direct or alternating. Direct Current (DC) flows in one direction only, while Alternating Current (AC) changes direction periodically. Electric currents… Read More
