in ac system the current wave form becomes zero for every
half cycle then how can we get continuous supply can any
one answer to this plsss
Answer Posted / shyamkr
basically the above answer is correct in all means.
but i like to add since our supply frequency is very high i.e 50 hz,so time period 'd be 20 ms.so for every 10 ms it passes through zero.due to persistence of vision of our eyes we can't able to see it what's happening to the bulb brightness n it seems to glow bright at all the times.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
