What is the total amount of inductance measured in millihenries?
The inductance of a coil is not related in any simple way to the length of the wire or other conductor of which it is wound. The inductance is at least as heavily influenced by the diameter of the coil.
The value of inductance for a coil with an air core is higher than the same coil with a ferrite core True or False?
false
What factors increase the inductance of a coil?
what factors on inductance drepends
What The property of a coil that makes it resist changes in current is called?
Inductance
What is an inductor and its current rating?
An inductor is an electrical component, usually a coil, designed to offer a specific value of inductance (measured in henrys). As the operating current of an inductor affects its inductance its inductance value (inductors are not linear devices, due to their hysteresis characteristics) is normally expressed for a specific range of operating currents.

How can I calculate the coil's self-inductance?
To calculate a coil's self-inductance, you can use the formula L ( N A) / l, where L is the self-inductance, is the permeability of free space, is the relative permeability of the core material, N is the number of turns in the coil, A is the cross-sectional area of the coil, and l is the length of the coil.
How does the permeability of a coil affect mutual inductance?
Since a coil contains numerous loops, more of the conductor is affectedÊ by the magnetic field. An increase in permeability of the core results in an increase in the inductance of the coil.
What two things is the value of inductance affected by?
There are four basic factors of inductor construction determining the amount of inductance created. These factors all dictate inductance by affecting how much magnetic field flux will develop for a given amount of magnetic field force (current through the inductor's wire coil): 1. Number of turns in the coil (N) 2. Length of coil (l) 3. Cross sectional area of coil (A) 4. Material (nature, or permeability) of coil: u(Greek meu) Inductance, L=(N^2 . u.A)/l
The value of inductance for a coil with an air core is higher than the same coil with a ferrite core True or False?
false
Inserting a soft iron core into a coil has what effect on the inductance of a coil?
increase inductance
How do you double the inductance value without double the number of the turns?
In addition to the number if turns, the inductance also depends on the length and diameter of the winding, the pitch (number of turns per inch), and the material of the core if there is one. Search on line and find an empirical formula for the inductance of a finite coil, and then work to tweak the other parameters to alter the inductance as required.
If number of turns of inductance double then its value?
"The magnetic field produced by each turn interacts with the field of other turns and multiplies the effect, causing the inductance of a coil of wire to increase by the number of turns (N) squared. Therefore, if you double the number or turns, you quadruple the inductance."
How do you measure inductance of a coil?
Type your answer here... By use an inductance meter or an inductance bridge
What is inductance comparsion bridge and its application?
It is used to measure the inductance of a coil of unknown inductance.
What factors increase the inductance of a coil?

How does the no of turns in a coil affect the production of electrical energy?
A coil doesn't produce electrical energy, but it can store it. For a given current (amperes), the energy storage in a coil is proportional to the coil's inductance, which in turn depends on the coil's length, diameter, and number of turns. With everything else staying constant, the coil's energy storage capacity increases when the number of turns increases.
