Inductance FAQs:


Q: Is inductance a property of an electrical conductor which opposes a change in current?

A: Yes.

Q: Is inductance approximately constant?

A: Yes.

Q: Is inductance proportional to the square of turns ratio?

A: Yes.

Q: Was inductance coined by Oliver Heaviside in 1886?

A: Yes.

Q: Is inductance the henry?

A: Yes, and with the unit symbol H, named in honor of Joseph Henry, who discovered inductance independently of, but not before, Faraday.

Q: Is inductance proportional to the square of the number of turns in the coil?

A: Yes.

Q: Is inductance called an inductor?

A: Yes.

Q: Is inductance also proportional to how much energy is stored in the magnetic field for a given current?

A: Yes.

Q: Is inductance used in flux calculations?

A: Yes.

Q: Is inductance ambiguous and is different whether you are calculating circuit parameters or magnetic fluxes?

A: Yes.

Q: Is inductance increased beyond the critical coupling?

A: Yes, and the peak in the frequency response curve splits into two peaks, and as the coupling is increased the two peaks move further apart.

Q: Is inductance a property of a conductor or circuit?

A: Yes, and due to its magnetic field, which tends to oppose changes in current through the circuit.

Q: Is inductance a function of coil geometry and number of turns?

A: Yes, and is independent of current.

Q: Are inductances often referred to as "partial inductances" to indicate that they must be used with care?

A: Yes.
