Static Electricity Flashcards
What is static Electricity
The study of charges at rest
Electric charge
Characteristics developed on a particle of a material which exerts force on other such particle and it accompanies the particle wherever it goes.
Electric field
The space around charged particles where electric force can be exerted on other particles
Types of charges
Positive and negative
Similar charges ___________
Opposite charges __________
Repel
Attract
What is a charge
It is an atom that has lost or gained an electron
Carrying charges is called
Electrification
Electrification by friction is called
Frictional electricity
Charge density
Charge per unit area.
Electrostatic induction
Phenomenon of polarization of charges in a body when a charged body is present or near it
Charges are usually concentrated at the
At the sharpest point or curve
Induction
To influence something without physical contact
What is coulombs law
It states that the force of attraction and repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them
Electric lines of force (electric Flux)
The are imaginary lines that shows where the influence reaches or is felt
Things about lines of force
-starts from +ve and terminates at -ve
-they never cross each other
-they are discontinuous
-they do not pass through conductor
