Science Electricity

Static Electricity

• charges built up on an object - at rest

• the accumulation of excess electric charge on an object

• electric charge at rest; generally produced by friction or induction

When do objects become charged?

• when they gain or lose electrons

• When electrons move onto them or off of them

In the law of electric charges, what do like charges do?

• repel

• attract

What are 3 ways objects become charged?

• Friction, Induction, Conduction

• Insulation, Terminal, Voltage

• Twist Locking, Polarization, Fuse

What is Friction?

• A force that opposes motion

• A force that opposes motion between two surfaces that are in contact

• Rubbing objects together causes an exchange of electrons.

What is induction?

• a charged object will exert its field on another object causing it to become charged just by putting the objects near each other

• the resistance that one surface or object encounters when moving over another.

• direct contact and transfer of electrons to a conducting material
