Charge

A gain of electrons causes a negative charge.

A loss of electrons causes a positive charge.

electric charge

- Electric Charge and Static Electricity

Electric Charge

Rule of charges: Charges that are the same repel each other. Charges that are different attract each other.

electric force

- Electric Charge and Static Electricity

Electric Force

An electric field is the area around a charged object where the object’s electric force influences other charged objects.

- Electric Charge and Static Electricity

Electric Force

The attraction or repulsion between electric charges

transferring charge

- Electric Charge and Static Electricity

Transferring Charge

There are three methods by which charges can be transferred to build up static electricity: charging by friction,

by conduction, and

by induction.

slide8

Friction

  • Rubbing two objects together to transfer charges
slide9

Conduction

Charged object must touch the other object – BOTH objects gain a charge which is the same.

slide10

Induction

Charged object must come near, but NOT touch the other object

– objects become charged oppositely.

Transferring Charge

An electroscope can be used to detect the presence of a charge.
