PI coil with resist is a good point?

[Punkt]

what for resist shold a PI coil have? have wire 2 coils arround 330uH 0.4wire 0.6

0.4 2.5ohm
0.6 1ohm

[Op04]

It depends what machine you want to build? What current you need? At tx pulse width or voltage and freq rate

[Carl-NC]

There are reasons to minimize coil resistance, and reasons not to minimize coil resistance. As Op04 says, it depends on the design.

For which detector is your coil made for?

[Punkt]

stand allrdy PI pulse induction otherwise i will type VLF or BFO

Let's try again...

There are reasons to minimize coil resistance, and reasons not to minimize coil resistance in a PI design. Different PI designs have different coil requirements, so it depends on what you are designing for. There is no one answer for PI.

Come again!?

why just a resist? why is not parasitic capacitance interturn, for example? why is not Q factor of the coil, for example?
while you sure know Ohm's Law for DC circuit, it's clear for me. sorry much, but Pulse time is not DC circuit current

Hi,

I know that it was made for a PI detector.... but for which detector (the name or model)? That was my question and would might give an answer to your question.
Further what type of coil is it? A mono PI coil or maybe a big frame coil?

it was more a general question. btw i forgott to tell the coil are simple round shape 280mm
