feeling like electric shock when touching metal objects?

recently one of my friend said he had a feeling or sensation of electric current zapping him whenever he touched any object or metallic surface though he was bit tensed about this phenomena i was really at ease because i too had experienced this few years back and i was aware that it was something that not needed to worry about...

i think its around early 2002 like always i parked the car inside and when i touched the car door to open i was terrified to see a small spark and a sensation of medium electric shock even before i touched the door i was stunned for a moment thinking whether there was any short circuit in the car and after a bit of courage i touched the car door for second time without any shock and i forget and thought incident as the mere illusion, but next day i encountered the same incident i could see a clear flash of spark between the metal surface of the door and my hand then i though it is something serious to look upon and then when i consulted my car electrician he found a wire dangling in the car dynamo after fixing it and replacing with a new voltage regulator in dynamo the problem was gone!

So why did i and my friend feel the shock?
simple! the faulty dynamo some how made to build up static electric charges in my body through the ignition key and steering and there was no way to discharge it as the floor of the car will be insulated by carpet and this build up of charge appears as high voltage and we sense the electric shock when ever we touch metal or grounded objects... it is said that upto 15,000 volts have been recorded and its common to have the static charge experience up till 5000 volts in people less than it people does not feel the sensation of electro static shock...

and coming to my friends case we were able to round up the culprit it was his computer cabinet which was below the monitor next to his feet and the missing ground wire in the wall socket that led to acummulate the static charge in his body and he used to feel mild electric shocks when he used to touch other metallic objects or ground.

it can be noted that static electric can be due to many reasons rubbing of your body on the seat or carpet, faulty circuit or many other reasons if you want to know what potential danger can static electric can pose see the below clip
