1
Q
Define Gauss’s Law
A
-The total flux through a closed Gaussian surface is equal to the total enclosed charge/ permitivity of free space
Relates the distribution of charge to the electric field.
2
Q
How can we find flux
A
flux = field strength x surface area
flux = E x A
3
Q
How is current density (J) calculated?
A
J = electric field strength x conductivity
4
Q
Define electrostatic potential
A
The amount of work done needed to move a unit of charge from one point to another
5
Q
Define dieletric
A
When an electric field is applied to an insulator, the internal charges in the material shift from equilibrium.
