Electricity And Magnetism

Front 1

the presence of electric charge (positive or negative) on the surface of a material

Back 1

static electricity

Front 2

movement of electric charges is called ______________

Back 2

electric current

rubbing electrically neutral substances causes a transfer of charge will give one substance a net positive and the other a net negative charge

Front 3

the SI unit of charge is the _____________

Back 3

coulomb

Front 4

one coulomb is equal to the charge of ________

Back 4

6.25 x 10^18 electrons

Front 5

equation of the Coulomb's Law

Back 5

Fc = (k.q1.q2)/r^2

where Fc = electrical/Coulomb force
k = Coulomb constant
q1 & q2 = charges
r = distance bet objects

k = 8.9875 x 10^9 N.m^2/C^2

Back 9

electric field

electric field is a vector quantity, it has magnitude and direction

Front 10

equation for electric field

Back 10

E = F/q

where F is the coulomb force (N)
q is the charge of the particle (C)
