how can we change the polarity of Alternating current rapidly? how frequency of ac can be controlled and changed easily?
Distinguish between nuclear power station with thermal power station for initial cost, starting period, cleanliness, and transportation of fuel
In single phase ac ups supply when current is measured with tong tester neutral current is found more than phase current.What is the reason?
hwat type of motor is used in thermal gas turbine hydro nuclear power plants and why
What happent when a AC motor(no break and starters ) stop and suddenly start . ? Starting current low or high?? Why?
why would amp draw on neutral wire be as much as amp draw on the hot leg.
we need a ntpc previous papers
