Why do you get an electric shock when touching any surface or a person?

Answer 1

All due to triboelectric effects (static electricity). If you walk across a rug (an insulator) on a dry day, when it is harder to neutralize the charge induced on your body, the rubbing action produces a net charge on your body (most likely positive)(an opposite charge will be induced on the rug you step on, to preserve charge neutrality), relative to the surrounding (door knob, another person who has sat still, your computer monitor, etc). The net charge will seek a lower-energy profile whenever possible, by discharging to the surrounding -- when you finger is in close proximity with the door knob or touching another person, for example. A human hair strand that you hold in your hand will be attracted to a CRT monitor, which is mostly likely negatively-charged. The personal static discharge is a much much smaller scale than what is happening in a thunder cloud, but painful nonetheless.

Answer 2

You do? I don't. I only get it when touching certain surfaces or persons, and then only under certain circumstances.

Those "certain circumstances" are, of course, a build up of substantial potential difference between that surface or person and me, which build up is in turn due to low humidity and static electricity.

Answer 3

I heard it is because of static electrcity. whatever it is i have the same problem too. wherever i touch these days i feel shock . every now and then. i am waiting for the seasonal change.

Answer 4

If this happens, then the appliance has a short circuit in it and is improperly grounded. It should be replaced immediately.

Answer 5

because of the static electricity.
