How to Coil an Inductor by the Length, Radius & Number of Turns to meet a Specific Inductor Value.

Characteristics of Components (PlayList)

Example 1
What is the inductance of a 20 turns coil wound on a 1/2 inch diameter (1.27cm) coil form with a coil length of 2 inch (5.08 cm)?

Example 2
How many turns are required for an inductance of 20uH to be wound on a 5 cm diameter coil with a winding length of 3.8cm?

Example 3
An inductor has a reactance XL of 250 and a series resistance Rseries of 2.5. Find component Q and the equivalent parallel resistance Rp of the inductor. If the inductor is shunt (parallel) with a 50k resistor Rshunt to form a circuit, what is the total parallel resistance Rt and the circuit Q (loaded Q) of this circuit?

Very simplified explanation and I understand now how to make my own inductor coil for my crossover dividing network for my Kenwood

Very helpfull to make pasif crossover audio

What about, in AC induction motor. How can we find the required number of turns

In 4B, the equivalent circuit for inductor is R and L in series. In this lesson, 4C, the equivalent circuit is in parallel. Please explain.

Calculation is not working, i can't understand what value in 25.4 ? And 22.9
My Inductor is 3 mH Drum bobbin indcutor Dia 8.67MM coil length 7.5MM So how can i calculate turns?

And when i calculate your formula with my calculator but value are different so pls can you explain in easy with calculator

Formula doesn't consider wire diameter, which is not specified in any event.
