Why, when you stroke a cat's fur, or comb your hair on a cold, dry day can you hear a crackling sound? Doing these things in a darkened room, you can actually see sparks. Explain.
Please explain to me! Thanx !!
Static electricity builds up with a positive charge on one of the objects and a negative charge on the other. The sparks in a dark room (it helps in VERY low humidity, also) are electrons (electricity) moving from the negative object to the positive object. You can see the same thing when sliding into a car on leather or fur seats on a cold dry day. In such a case I have been shocked when I place the metal key into the ignition socket of the car.
Thankyou soooo much!
