Static Electricity Instructor: Shelia Chase

Static Electricity Build up (accumulation) of charges on an object. Opposite charges attract; like charges repel Lightning is caused by static discharge

Cause of Static V1c61Q7qU-s

Charging by induction Rearrangement of electrons on a neutral object caused by a nearby charged object.

Charging by Conduction Electrons are transferred between two objects that are touching.

Charging by Friction Electrons are transferred as one object rubs against another.

Conductor Allows electrons to move easily through it Examples: silver and copper (metals) Insulator Does not allow electrons to move easily through it Examples: plastic and wood (nonmetals)

Grounded Connected to the earth Electroscope Detects electric charges with two thin metal “leaves”

In your notes, draw a picture to represent what would happen if a positively charged rod was brought near a neutral object. By what method is this object being charged?

Physics is fun!
