electricity 1 quiz

Electricity was proposed by

Charles Francois

He was interested in the

Attraction and repulsion of objects that occurred after they been rubbed

Charles proposed that

Electricity was the interaction between two electrical fluids

He concluded they were called

Vitreous and resinous

He said fluids were separated by

Frictional forces

One fluid model proposed by

Benjamin Franklin

He claimed electricity was only one fluid that could be present in excess or absent from the body

Attraction between opposite charges

( positive can give access fluid to the )

Negative so they become neutral

Positive object has

More fluid

Negative object has

Less fluid

Neutral object has

Same amount

Protons can’t

MOVE from the atom at all

The electrons can

MOVE

Negative

An object with more electrons than protons

Positive

Object with fewer electrons than protons

Opposites or unlike charges

Attract ( negatives attract positives )

( positives attract negatives )

Objects that have the same charge

Repel each other

Two neutral objects have

No effect on each other

Charges objects

Attract neutral ones

Objects become charged when there is a

Transfer of electrons / negative charge

Two ways to charge an object

Friction

Conduction

Charging by friction

Occurs when a neutral objects of different materials are rubbed together

Charging friction occurs because

Electrons are free to move one object to another

The object losing electrons

Becomes positive

The object gaining electron becomes

Negative

EXAMPLE

running a comb through ur hair

Charging by conduction

You can permanently charge an object by

Touching it’s with another object

Electrons will flow to or from

The neutral object

If u touch the neutrals object with a negatively charged one it will

Become negative

If you touch a neutral object with a positive charged one the object will become

Positive

Charging by induction

When u bring a charger objects near a netutral object but not touching it you can induce the opposite charge on the neutral object

Induction is a temporary charge when the charged object is removed everything goes back to normal

SUMMARY

Charging by friction

Two objects rub together and end up with opposite charges

They attract

CHARGING BY CONDUCTION

Two objects touch and end up with the same charges

They repel

Charging by induction

Two objects are brought close together and the opposite charge is applied

They attract aswell

Temporary change
