|Why does capacitor block dc supply?
|why semicondoctor use in HT cable?
|I have 2 transformers in two different plants, both are
without OLTC but i am facing problem of voltage fluctuation
at LV side from only one transformer.
i have to change its taps manually twice in a day.
Another transformer delivering voltage is ok.
Please guide me about the problem
|if the 10 hp motor name plate indicates rated current as
13.6 amp the what will be the thermal relay setting?
Why? And in how much time relay will trip at the set
|why 3phase is 440v but where as we get phase voltage 220v,we
have to get 220*3=660v.can u pleas give in detailed

|why does a dc machine has high efficiency while working as a
generator than as a motor
|when voltage gets down the current of motor increases. but
according to Ohm's law voltage is directly proportional to
current. plz explain
|Why Lighting transformers are used? what will be the
current if lightings connected through direct raw power?
|Pure inductive ckt takes power from AC when
1. Applied voltage and Current increases
2. applied voltage and current decreses
3. voltage decreases and current decreases
