usually ac i/p is changing in the range between 190v-250v,
but actually our devices are designed in such a way that to
allow only constant flow, because of this variation you will
not get desired results, some times device may burn. so we
need to provide constant flow. voltage regulator , regulates
the flow and allows constant flow. zener diode is used as a
regulator.
