A record is dropped vertically onto a freely rotating (undriven) turntable. Frictional forces act to bring the record and turntable to a common angular speed. If the rotational inertia of the record is 0.

Find the displacement current through a parallel-plate capacitor. Assume that V is the voltage across the capacitor at any instant. Express your answer in terms of the variables C and dV/dt.

Suppose the Earth orbited the Sun in 4 months rather than 1 year, but had exactly the samerotation speed. How much longer would a solar day be than a sidereal day? Mercury's siderealday is 58.6 days and its orbital period is 88 days.

While an emf source supplies energy to a circuit, that energy is dissipated when the current passes through resistance. In dealing with circuits though, it is often more useful to know the rate at which energy is changing.
