In an alternator, if the frequency is f, the rotational speed is N and the number of poles is P then
A)
P=120N/f
B)
P=120f/N
C)
P=N/120f
D)
P=f/120N
For an alternator, f=PN/120, so P=120f/N.

Inductive reactance is measured in ohms because it
A)
reduces the amplitude of alternating current
B)
increases the amplitude of alternating current
C)
reduces the amplitude of direct current
D)
has a back emf opposing a steady direct current
Inductive reactance is expressed in ohms because it opposes AC current in the same dimensional way as resistance.

Capacitance increases with
A)
increase in plate area and the distance between the plates
B)
reduction in plate area and the distance between the plates
C)
increase in plate area and decrease in the distance between the plates
D)
decrease in the plate area and the value of the applied voltage
Capacitance C=εA/d, so it increases with plate area and decreases with plate separation.
