Electro Statics Flashcards
What is this
The study of stationary charges
What is atoms made up of
And how do we know it is +ve or -ve charged
Matter is made up if atoms which consist of electrons ,protons , neutrons
If an object has excess electrons it becomes negatively charged
If an object has dificiency electrons it becomes positively charged
How does a object get charged
To cahrged an object friction is need
The object is rubber against another object which results in the transfer of electrons
How do u create friction
What us this called
The object is rubber against another object which results in the transfer of electrons
This process of charging a material by rubbing us called triboectric charging
What is the symbol of charge
Q
What is cahrge measured in
Coulombs
What is the constant charge of an negative and positive electton
Electron charge - (-1,6x10-19)
Positiev charge - (1,6x10-19)
What us net charge
The total charge in a given objects
How do u calculate net charge
Add the charges
Qnet= Q1 + Q2 ….
For any calculation what must Q be in
Q must be jn coloumbs
What if Q us given as the following
mC
uC
nC
pC
How do u convert to C
mC- (x10-3)
uC - (x10-6)
nC - (x10-9)
pC - (x10-12)
What does the principleof cinservation of charge state
In a isolated system the net charge remains constant after any physical change
What happens when to charged objects come into contact with each other
What happens when thet separate
when to charged objects come into contact with each other they ashre theru charges equally
when thet separate they have the same amount or charge
How do u calculate the new charge after two objects who came into contact ,seprate
Qnew=Q1 +Q2..

n
What deos principle cahrge of quantization state
Every cahrge in the universe is an integer multiple of the electron charge
