What is electric flux?
Electric flux is a measure of the electric field passing through a surface, considering the field’s orientation with respect to the surface normal.
What is a Gaussian surface?
A Gaussian surface is an imaginary closed surface used to simplify electric field and flux calculations, particularly in applying Gauss’s law.
What is Gauss’s law?
Gauss’s law states that the electric flux through a closed surface is proportional to the net charge enclosed by that surface.
What are equipotential surfaces?
Equipotential surfaces are 3D spaces where every point has the same potential energy, either electric or gravitational, and are always perpendicular to field lines.
What is the principle of superposition in electrostatics?
The principle of superposition in electrostatics states that the net electric force on a charge is the vector sum of forces from all other charges.
What is an electric potential difference?
Electric potential difference, or voltage, is the work done per unit charge to move a charge between two points in an electric field.
How do you calculate the work done in moving a charge through a potential difference?
To calculate the work done in moving a charge through a potential difference, use the formula W = q * V, where W is work, q is charge, and V is voltage.
How does a dielectric affect the capacitance of a capacitor?
A dielectric increases a capacitor’s capacitance by raising its dielectric constant, allowing it to store more electrical energy in the same space.
What is a polar molecule?
A polar molecule has an uneven distribution of charges due to differences in electronegativity, resulting in a molecular dipole moment.
How do you calculate the equivalent capacitance of capacitors in series and parallel?
In series, 1/Ceq = 1/C1 + 1/C2 +…+ 1/Cn. In parallel, Ceq = C1 + C2 +…+ Cn. Series Ceq is smaller, while parallel Ceq is the sum of individual values.
