What does Gauss's Law for Electricity state about electric flux and charge?

Gauss's Law for Electricity states that the electric flux through a closed surface is proportional to the charge enclosed within that surface.

Fill in the blank: Gauss's Law for Magnetism indicates that magnetic monopoles ___ exist.

Do not

True or False: Faraday's Law of Electromagnetic Induction states that a constant magnetic field creates an electric field.

False. Faraday's Law states that a changing magnetic field creates an electric field.

List the four Maxwell's equations.

1. Gauss's Law for Electricity, 2. Gauss's Law for Magnetism, 3. Faraday's Law of Electromagnetic Induction, 4. Ampere-Maxwell Law.

In the equation for Gauss's Law for Electricity, what does the symbol ρ represent?

The symbol ρ represents the charge density.

Ampère's Law with Maxwell's Addition accounts for ___ in the context of changing electric fields.

Displacement current

How does Maxwell's modification of Ampère's Law ensure consistency with the continuity equation?

By adding a term for the displacement current, which accounts for changing electric fields, thus linking the changing electric field to the current through the loop.

The equation for displacement current density (J_D) is given by J_D = S(∂D/∂t). What do the symbols represent?

J_D is the displacement current density, S is the area of the capacitor plate, and ∂D/∂t is the rate of change of electric displacement.

True or False: Displacement current involves the movement of charge carriers between capacitor plates.

False; displacement current does not involve the movement of charge carriers but represents a changing electric field.

What is the significance of displacement current in the context of capacitors?

Displacement current explains the changing electric field in a capacitor when it is charging or discharging, even in the absence of actual charge flow between the plates.

Electromagnetic waves consist of electric and magnetic fields that change ___ and are ___ to each other.

Sinusoidally; perpendicular

True or False: Electromagnetic waves can be produced by stationary charged particles.

False; Electromagnetic waves are produced by accelerated charged particles.

The equations for a plane progressive electromagnetic wave are E = E₀ sin(Ω(t - x/c)) and B = B₀ sin(Ω(t - x/c)). What is Ω?

Ω = 2πv, where v is the frequency of the wave.

What is the speed of electromagnetic waves in a vacuum?

The speed of electromagnetic waves in a vacuum is 3 x 10^8 m/s.

The Poynting vector S is defined by which expression?

The Poynting vector S is defined by the expression S = 1 / μo (E * B).

Transverse

True or False: The energy in electromagnetic waves is unequally divided between electric and magnetic field vectors.

False. The energy in electromagnetic waves is equally divided between electric and magnetic field vectors.
