Inductor Diagram. Typical schematic diagram of an inductor a chokeor reactor. Core is nothing but a material on which the wire is wounded as shown in the above diagram.
There are a few different ways to place an object into your drawing. Likewise we can also say that the voltage leads the current by 90 o. Therefore in such a case the voltage is l di dt and the current is i.
However the voltage across each conductor will be the same.
An inductor always tries to block ac and allow dc. Inductors are extensively used in alternating current ac applications such as radio tv and communications equipment and in these systems how inductors react to ac signals of different frequencies is very useful chokes. This current depends upon the inductance value. There are two main classifications of inductors air core and iron core.
