static and current electricity quiz

Def/ex of static electricity

The buildup of electric charge caused by an imbalance between electrons and protons

Ex: the transfer of electrons between clouds and a object on the ground. known as lighting

Types of charging

Induction:

Objects become pos and neg withing touching but close

Es from cloud repel es on ground, tree (+)

and contact

Objects + and - causes by contact

Rubbing ball on on hair

Hair is (+)

Balloon (-)

Based of Es affinity, ability to attract and keep es

Partial mass charge and location

Neutrino 1,0,N

Protron 1,1.N

Es 0,-1.O

Law of charges

++, charges hair and lighting rod

-,-, es in clouds and lighting rod

+-, hair and balloon

Two apps: electrostatic air cleaner

Used to filter pargiles form air

Two parts of the cleaner have (-+) charge depending on what terminal of the circuit it's connected to

The electric charges create an electric field

The dusts receives a (-) charge

Electric field removes electrons from air

Fre electrons attract to the dust

Dusts goes to + part

Lighting rod

Used to transfer es from clouds

Clouds form (-) when particles rubs together

Es in rod repel into ground, rod +

Ionic path made btwen two, air now conductive

Lighting stricks

Lighting process

Dusts rub together giving bottom (-)

Es repel other es objects in ground

Ionic pathway, air conductive

Electronic move down, object +
