Transformers are the device which is capable of receiving AC power at one voltage and delivering it at another voltage. In this way  transformer help in achieve better transmission efficiency, while transferring the power over longer distances with high voltages,In this article include transformer MCQs ...Read More

What is an insulator? It is a material which cannot conduct electrical current. It have high resistivity and low conductivity. Atom of the ins have tightly bound electron and therefore cannot move throughout of material. Due to the electrons are static and not freely ...Read More

What is Skin effect?The distribution of current over the cross section of the conductor is uniform in DC only. In alternating current flow through a conductor does not distribute uniformly but it will concentrate near the surface of the conductor. In fact, in AC ...Read More
