A practical transformer has different types of losses like core loss, copper loss, etc, that decrease the efficient transfer of energy from the primary to the secondary coil. Eddy current loss is one of...
A fuse is a device used to interrupt the current flow during an overload or short circuit to protect the electrical system from damages due to the excessive current flow. In a circuit, a...
What is an inductor? An inductor is a coil consisting of an insulated wire wound over an air or iron core with a fixed number of turns. It stores energy in the magnetic field...
A single fan and light control using an individual switch is a very commonly used wiring circuit in house, offices, etc. In the circuit, the phase line is connected parallel to the one pole...
Isolator and circuit breaker both are electrical devices that are used to open or close a circuit. But they are different based on its use, construction, and operation. Here we discuss its few main...
In electrical wiring, a master switch is a switch that can ON or OFF or both ON/OFF a group of loads irrespective of their individual ON/OFF switch control. Using a master ON circuit a...
What are AC and DC supply? AC – Alternating current is an electric current that periodically reverses its direction of current flow. One complete cycle of an AC supply consists of a positive half-cycle...
Protection relays are protective devices used to sense various faults and give signals to circuits (master trip circuit) that execute various functions on the event of a fault, like provide an indication, data to...
A circuit breaker is an electrical switching device that is used to protect and control the electrical system that can be operated either manually or automatically. The mechanical power to operate most high voltage...
What is an Electric motor? An electric motor is an electrical machine that converts electrical energy into mechanical energy. What are ac and dc motors? The electric motor that converts the AC electrical energy into...
