Answer 1

The average values of vL(t) and vD(t) are equal in magnitude and opposite in sign.

Answer 2

The rms value of vD(t) equals the rms value of the source voltage.

Answer 3

The average value of vD(t) becomes zero if the diode orientation is reversed.

Answer 4

The average value of vD(t) is zero because the diode conducts for half the cycle.
