CAPACITOR AND INDUCTOR

CAPACITOR AND INDUCTOR

CAPACITOR
-A capacitor is a two-terminal, electrical component. Along with resistors and inductors, they are one of the most fundamental passive components we use. You would have to look very hard to find a circuit which didn’t have a capacitor in it.


A capacitor, we are familiar with this thing because we use to it into our power supply. We use capacitor to stored energy in our power supply.


INDUCTOR
-An inductor is a passive electronic component that storesenergy in the form of a magnetic field. In its simplest form, an inductor consistsof a wire loop or coil. The inductance is directly proportional to the number ofturns in the coil.





The standard unit of inductance is the henry.

In a capacitor, the formula is expressed as “the current in a circuit is in proportion to the time rate of change of the voltage across it.

written as:

i=c(dv/dt)

In series and parallel capacitors, they are combined in the same way as conductances.

An inductor formula states that the voltage across it is directly equitable to the rate of change of the current through the circuit.

The formula is written like this:

v=L(di/dt)

In solving inductors in series and parallel, it is the same as combining the resistors in the circuit, which is in series or parallel.
