The capacitors and inductors are two reactive components. This implies that they react, or oppose each other, changes in electrical variables.

A capacitor opposes, for example, or reacts, to any change in voltage level. Inductors, on other hand, “react” to changes in current flow. This reactive effect has a deep relationship with the frequency. When frequency of the applied voltage to an inductor is enhanced, the inductor’s opposition to AC flow of current increases. This all happens because the energy capable of being stored in the electromagnetic field of inductor (its inductance value) stays constant, but the time period of the applied AC-voltage gets decreases. when the AC time period is decreased, few energy is required from the inductor’s electromagnetic field to oppose the voltage alternations. Take this example, when it would take 10 times the energy to oppose 100 volts for 10 seconds than it would to oppose the same voltage for 1 second.

The same rule applies with an increase in the frequency amd decrease in time period of the applied AC. We can state this basic principle by saying that
