I have read this
http://communication.howstuffworks.com/telephone4.htm
And me and my 3 next door neighbor's are curious to set up our own phone network.
We all have spare phones , crimping and stripping tools ...etc
And we are wondering if we can make our own network.
Forget the ringing for a second. Can we just use a 9 volt battery and hook all
the greens together and reds together.
Then hook the green bunch to positive and red to negative of the battery.
Or must I use a larger battery for more phone's then two (I don't think so because all of these are hooked in parrell )
But the more phones I add in parrell the less current for each phone while the voltage will stay the same.
But what about the 300 ohm resistor? I don't quite understand why they use it and what I should use.
I would like to know what voltage and resistors I need for 100 or 1000 ,...etc phone's their should be some formula for it ?
