Answer:
d.Electric flux through a closed surface and charge enclosed by the surface
Explanation:
Gauss' Law states that the electric flux through a closed surface is equal to the total charge enclosed by that surface divided by the electric permittivity.
[tex]\int\vec{E}d\vec{a} = \frac{Q_{enc}}{\epsilon_0}[/tex]
Therefore, correct answer is d.
a -> Ohm's Law.
b -> Faraday's Law.
c -> [tex]\tan\phi = \frac{\omega L - 1/\omega C}{R}[/tex]
