So, if the 100 Hertz has a wavelength of 3e+6 meters, total amount of antenna should be 729. Is this correct ?
If i use big diametar (some 5 cm pipe) can i use double or triple or more windings, on 1 metar pipe length to get this work ?
Good day !
If i want to pickup frequency range from 10 - 100 HZ, what kind of antenna do i have to build ? ( im using isolated copper wire (0.5)).
I need just antenna design, for now ....
Basicly, let me put it this way. If you have source, which is emmiting this freq. range, how to pick up...
what might be the function of capasitor
One more question regarding AC capasitor (20 microF).
If i charge AC capasitor with 50V of direct current i can measure ( direct connected on multimeter ) 2mA of DC.
1.) Is it possible that this kind of capasitor can "produce" AC current. I have writen...
function of capasitor
Yes, that's it :-) I have made simple example and it's working perfect.
One more thing regarding caps capasity.
Do you know the hardware difference between 25microF and 50 or 100microF ?.
Is the dialectric same or not...
Am asking this becuse i want to make my own ( just...
difference between ac dc capacitors
Hi Tom,
I agree and i was thinking about that. But if they are HF capasitors then they are producing greater AC power as "standard" capasitors or ?
What is the difference betewwn AC and DC capasitors and how does AC capasitor works?.
Im asking this becuse till now i have look into capasitor as into "charge box" which can be charged with some DC power and this will result into high voltage and low power. So i dont understand what shoud AC...
i dont understand what is the 9V u r talking about ... ?
I have used standard 9V battery just as test. On this battery i can make measurments on VΩmA - COM connections but for 1.5 camera battery i have to switch to unfused plug. Why ?
Anyway, thank you for your replays !
--- The camera is working normal.
--yes
-- If i connect COM and VΩmA then i get no measurment
-- If i connect the same battery to COM and 10ADC ( on the same scale ) i get 50mA
-- If i connect 9V on the COM - VΩmA way then i get 50mA
So, i dont understang why i have to measure (when i make...
When i make measurment on my 1.5 battery ( battery from some camera ) on the scale " 10 ADC ( unfused )" i get 50mA. If i do the same thing but connected to the fused part of the voltmeter i get no result.
I dont understand why is this happening becuse im measuring the voltage from DC battery...
