The voltage is actually at its maximum value for very little time and has a value of zero ______ times per cycle.

In an alternating current that follows a sinusoidal shape, the voltage peaks briefly but spends two moments each cycle at zero. If you model it as v(t) = Vmax sin(ωt), the zeros occur when sin(ωt) = 0, i.e., at ωt = 0 and ωt = π within one cycle. That gives two zero-crossings per cycle. So the voltage is zero two times per cycle.
