Static Electricity

Static Electricity

Static Electricity is the build up of electrical charge.

Static Electricity

most objects have chaged particles and so have equal amounts of positive charge and negative charge

Static Electricity

If there are more negative charge on the object then its statically charged

What happens when it a statically charge object is near a balanced charged object?
