Define inductor and inductance of inductor with its unit?

Answer 1

ohms

Answer 2

An inductor is a device that resists a change in current. The windings in the inductor form a magnetic field that serve the maintain the electric current by bucking an increase in current or by sustaining a decrease in current.

Inductance is measured in Henry's, after Joseph Henry, who discovered electromagnetic induction around the same time that Michael Faraday did.

The equation for inductance is ...

di/dt = V/H

... where di/dt is the rate of change of current, in amperes per second, V is voltage, and H is inductance in Henry's. The Henry is a large value of inductance. Typical inductors are measured in micro henrys or in milli henrys.

Answer 3

• A henry (H) is the SI derived unit of inductance. Henry is defined as the inductance of a circuit, in which changing of current with the rate of one ampere per second creates electromotive force of one volt.
• The SI unit is SI measurement system.
• SI unit defined as any of the units adopted for international use under the Système International d'Unités, now employed for all scientific and most technical purposes.
• There are seven fundamental units: the meter, kilogram, second, ampere, kelvin, candela, and mole; and two supplementary units: the radian and the steradian.
• All other units are derived by multiplication or division of these units without the use of numerical factors.
