The Making of Choke Coil !

[learning]

Can you tell me how to make choke coil at home ?

Thank you !

How much current? How much inductance?

How much current? How much inductance?

As I like to make choke coil for power supply to audio amplifier as I don't know how much current and inductance are required !

Then it's rather hard to make the coil, isn't it?

How much it would be harder that does not make any sences to me as I know that I have to make it. So I have to make it with minimum configurations (default).

OK, let us turn the question around:

I have to make a wooden box, the box has to hold some equipment.
How big should I make the box? I dont know the size of the equipment, so I have to make the box with the minimum default size.

An easy problem, isn't it?

How much current? How much inductance?

Current - 1Amp
Inductance - 1 Wb/AMP

Current - 1Amp
Inductance - 1 Wb/AMP

The normal unit of inductance is the Henry.

I suggest you first describe the amplifier you're trying to build - presumably it's a valve one?, so why not just buy a choke when you buy the mains and output transformers.

Hello there,


Although that is an acceptable way to describe inductance it is much more common to describe it in actual Henries. Thus, you need a 1H inductor.
That's quite a large inductance really. Are you sure you need it that large?

Seriously give some ideas making of choke coil !

 

[RMMM]

It depends on the rating.

You can make a choke coil by taking a pencil, and wrapping copper wire around the pencil.

The thickness of the wire, and the number of wraps(turns) all depend on what you are trying to choke.

Different frequencies need different construction. There are truly ENDLESS recipes.

You can use air as a core, iron, powered iron, wood, lead, ferrite, shrimp, chicken necks, your kid sister.. All kinds of stuff.

And, like I said, the thickness of wire, and the number of turns all depend on what it is being used for.

Is this for your speakers?
