Charge moves if you scuff the rag with your shoes,[link widoczny dla zalogowanych]
Let's assume that socks and shoes move the same amount of charge. It is a tiny amount of charge,[link widoczny dla zalogowanych], which gets stored in the capacitor formed by our body.
This stored charge gets discharged across the resistance from the body to the surroundings,[link widoczny dla zalogowanych].
The lower the resistance,[link widoczny dla zalogowanych], the faster the discharge. If the resistance is low enough,[link widoczny dla zalogowanych], the charge wont even create a noticeable voltage change in the capacitor,[link widoczny dla zalogowanych], because it is discharged faster than it is created.
So,[link widoczny dla zalogowanych], if you are wearing shoes, the resistance is big enough to get a noticeable charge stored up.
Wearing socks,[link widoczny dla zalogowanych], the resistance is lower (thinner layer not made of a very good insulator),[link widoczny dla zalogowanych], and the charge dissipates as soon as it is generated.
The creation of static electricity is called the tribologic effect.
I know from experience you can generally calculate the high voltage as 1kV/mm gap or 1 million volts per meter gap,[link widoczny dla zalogowanych]. With a pointy antenna it takes less voltage than large round balls to breakdown due to the electric field fringe effects,[link widoczny dla zalogowanych].
Anyways,[link widoczny dla zalogowanych], it was a good 2 inch arch using the hotel key to the door handle or 50 mm = 50kV
But back in the 80's when I was Test Mgr at Burroughs,[link widoczny dla zalogowanych], we implemented ESD controls in mfg. and had instruments to measure body charge voltage. After ground yourself and raising one leg, yu could generate a couple hundred volts easy. This is due to the distribution of charges in the body and changing your body position
Q=CV means changing the body capacitance changes the voltage for the same charge. So that explains why even when not causing a friction or tribilectric charge up you can create an electric field from slow motion,[link widoczny dla zalogowanych]. Xmas Tinsel on an old tube type TV set is the easiest way to see the effects of an electric field with your hand and the tinsel pointing directly towards the TV,[link widoczny dla zalogowanych].相关的主题文章:
