Inductance | What is inductance? | What is an inductor?

According to Faraday’s law of electromagnetic induction, “Whenever there is a change in current flowing through a coil, a change in magnetic field is produced which induces a voltage across the coil.” A coil is nothing but a twisted wire. When such a coil is formed out of a wire of certain length and cross-sectional area, it acts as an inductor. (more…)

Electric Resistance | What is Resistance?

Resistor

As we know the current is the flow of free electrons in a material from higher potential to the lower potential. During this flow, few of these electrons collide with other atoms in the material and lose their energy in the form of heat. These collisions cause a drop in potential across the material.
