what is electrostatics? Electrostatics is the study of stationary electric charges or fields as opposed to electric currents
what happens when a glass rod is rubbed with a silk cloth? the glass rod acquires positive charges and the silk cloth acquires negative charges
Like charges repel or attract one another? repel
Unlike charges repel or attract one another? attract
A neutral object has a net charge of? zero
If the plastic rod and fur are initially neutral, when the rod becomes charged by the fur, a negative charge is transferred from the____to the____ a negative charge is transferred from the fur to the rod
what is charging by contact? This is when a charged object comes into contact with a neutral object and some charges are transferred
when two solids are rubbed together, they develop? charge through friction
what is electrification? electrification is the process of making a system use electricity when it did not use it before
Electrification due to friction is known as? frictional electricity
What are the two types of charges? positive and negative
when matter is neutral, the number of positive and negative charges are equal
what is an electrostatic series? if two materials are rubbed together, the former in the series acquires the positive charge and later the negative charge
what is electrostatic induction? it is the process of polarization of charges in a body, when a charged body is present near it
what does electrostatic induction entail? it involves charging a body without touching it
what is additivity of charge? it is the ability for charge to be added by simple algebra rules
Electric charge is an integral multiple of _________ charge minimum charge
The minimum charge exist on an? electron
The material that is transferred during electrification is? an electron
_____ is the smallest value of charge? e
what is elementary charge it is the smallest value of charge
what are the two types of electric charges? positive (+q) and negative charge (-q)
Like charges repel
unlike charges attract
The necleus of atoms is ________ charged Positively
Electrons are _________ charged negatively
Charges in an atom are normally, neutral
Which is heavier between electrons and protons? protons are 1837 times heavier than electrons
The loss of electrons develops? positive charges
An excess of electrons develops? negative charges
what is a conductor? A conductor is a material through which electric
what is an insulator? an insulator is a material that electric charges cannot move through easily
what is an electroscope? an electroscope is a device used to indicate the existence of charges
what is a good conductor? a good conductor is a material that electron are free to move around
what makes rubber and glass such good insulators? the electrons are tightly held by the nucleus
Electrons can be forced to move across an insulator when _______ is applied electric field
what is dielectric strength it is the maximum electric field an insulator can withstand without becoming a conductor
what is a semiconductor? a semiconductor is a material which converts from a insulator to a conductor with little stimulation
what is a superconductor? a superconductor is a material which presents no resistance to the movement of the charge through it
