Regulator is nothing but a series circuit of resistances.
Let regulator has three points.
At point 1, All the three resistances are in ciruit. The
eq. resistance increase, current decreased & speed
decreased.
At point 2, only two resistances are in circuit. The eq.
reistance is decreased, current increased speed of fan is
increased.
At point 3, only one resistance in ckt. The eq. resistance
is again decreased, current increased. speed of fan is
again increased.
