Decribe the three ways an object can attain a "static" charge.?

Answer 1

You can pet a cat, or even rub your own hair to build up static. It has to be very low humidity to hold the charge, so it only really works when the weather's dry.

Answer 2

Conduction - If a neutral conductor touches a charged conductor, they'll share the charge.

Induction - If a neutral object is brought near a charged object, the charges in the neutral object will rearrange slightly as they are attracted and repelled from the charged object.

Friction - When different substances are rubbed together and then separated, one may keep more of the electrons, thus charging both objects. It's really the separation that matters, more so than the friction - but that's the name often used. This is the method that people employ when they rub balloons on their heads.

Answer 3

Static charge is obtain by friction of two materials that are dry and conducive to sustain a charge , like a glass rod rubbed with dry cotton or velvet , a toy balloon rubbed on you hair or sweater , air rushing by a moving car or airplane , a shop vac being used on a fiber glass boat , rubbing your sock feet on the carpet , the silky under garment of a woman etc....

Answer 4

1) By friction.
2) By contact with a charged object.
3) By being inside an electric field ? (not sure of this one)
