Inductance | What is an inductor?

Inductance A conductor carrying current produces a magnetic field around it. This magnetic field follows a circular path. When the same conductor is wound over a cylindrical solid core, the magnetic field formed around it amplifies. Any change in the rate of current flow through this conductor causes a change in the magnetic field, thereby … Read more

Transformer Action

Transformer action is a phenomenon by which EMF(Electro-motive force) is induced in from one coil to the other coil by electro magnetic induction. It is the basic principle of electric transformers. When a certain AC voltage is applied to a coil, current, proportion to the applied voltage and inversely proportional to the impedance, flow through … Read more
