    following are questions for an online quiz. i already chose my answers but not 100% that i am right. so i figured that i'd put it up here and have ppl double check my answers. thank you for the help

    T/F The voltage across a capacitor is proportional to the time-integrated current that charges the capacitor.
    my answer: T

    Mark the Correct Statements:
    1. The behavior of an inductor (coil) is described by Faraday's law.
    2. A change of the current through the coil causes a magnetic flux change.
    3. The emf induced by an oscillating current in a coil reduces the current oscillations.
    4. Henry = Volt*second/Ampere
    my answer: 2,4

    Voltage and current oscillations in an RLC circuit are damped due to heat dissipation that occurs in (choose one):
    1. the capacitor
    2. the resistor
    3. the inductor
    my answer: 2

    T/F In an RLC circuit the energy oscillates between the capacitor and the inductor.
    my answer: F

    In an RLC circuit the energy is stored in (multiple answers):
    1. the electric field of the capacitor
    2. the magnetic field of the capacitor
    3. the electric field of the inductor
    4. the magnetic field of the inductor
    my answer: 1, 4

    Mark the Correct Statements:
    1. In the under damped RLC circuit the oscillation period is given by RC.
    2. The amplitude decay of the current for both the under and critically damped case has a characteristic time 2L/R.
    3. At critical damping the current does not oscillate (no zero crossing).
    4. In an over damped RLC circuit the current decays fastest to zero.
    my answer: i have no bloody idea
