Are you sensitive to static electricity ?
Do you feel that the telephone line voltage ( 40-60v ) cause an annoyance to your body ,
when you hold both wires " electricity passes from your body ?
Well you can measure your body resistance and find how sensitive you are ...
Set your DMM at the 1M Ohm , and wait about some seconds to some minutes , until the reading to stabilize.
For best results , seat on a chair , and place its hand over the knee of your legs. ( by holding the DMM leads as well ) , keep your knees at 20cm distance , and place your hands over the trouser ( Not naked skin.)
My results , 650 - 700K Ohm ..
Post yours too , but do not take an fast measurement ... and confirm it with two DMM if possible.
Have fun , and report back.
