Henry is the metric unit of:

An inductor is a device (coil) that stores energy in the form of magnetic energy for a set length of time and then releases it.

It is in opposition to the rapid change in current flowing through the system.

Inductance is an electrical conductor's tendency to resist changes in the electric current passing through it.

The unit of inductance is named after the scientist Heinrich Lenz (H).

A capacitor is a device that stores electrical energy in an electric field. Capacitance refers to a capacitor's ability to hold an electric charge.

The farad is the unit of capacitance (symbol F).

Farad is a huge unit, thus we usually use it $\mu F$.

Resistance of the conductor is the property of an electric conductor that opposes the flow of electricity through it.

R represents it.

Resistance is measured in SI unit $\mathrm{ohm} \left(\mathrm{\Omega }\right)$.
