In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
GE,
1 4361why always out of the 3 phase(RYB) of supply, in Y phase w.r.t the voltage is higher? on R & B phase the voltage will be lower as compared to Y phase?
1 64036.6 KV /.415KV Step down trf. we can get 6.6 KV from primary by applying .415 KV secondary side by same TRF.
3 7774how we control automatic generator i'e with to supply (main supply and local generator) when the main supply was break to supply the local supply automatically to begin supplying power.I now this control circuit is the combination of contactor time delay contactor switch and overload relay .but my question is how we combine those component thank you
