The power rating of a device is the maximum magnitude of power that can be allowed to operate by the device. Active power, Reactive power, and Apparent power are rated in watts (W), Volt-ampere reactive (VAR), and...
An electrical circuit breaker is an automatic switching device that is installed for the safety of the electrical system. It protects an electrical circuit from electrical damages caused by conditions like overload, short circuits,...
Earth, Ground and Neutral all three are similar to each other but often confused or referred one as other. Still, it has the difference to term it separately as they serve for different purposes....
Earthing is a connection between electrical devices to the earth through a low resistance path, which provides a discharge of the electrical energy directly to the earth. Considering the safety reasons earthing is one...
Materials made of metals will possess the property of electrical conductivity, an electrical conductor allows electric charge to flow through it. Silver is the most electrically conductive element followed by Copper, Gold, Aluminum, Zinc,...
Fuse is a sacrificial electrical safety device used for overcurrent protection. It will isolate the circuit from the source when the current flow exceeds its limit. As the Fuse is not just an electrical contact, it...
In series connections, we can always encounter with a popular question, which bulb will glow brighter when the lamps have different power ratings. We know that the current through a series path will be...
Phasor form conversion is the method of changing the representation form of a phasor. A Phasor is a rotating vector in a complex number form which expresses the magnitude and its phase. Sinusoidal signals...
