question is wrong .. Its not AC
voltage or DC voltage its AC
CURRENT and DC current i.e
alternating current and DC is

what is soft starter?working principle?where it can use?
WHY WE USE 4-20mA
can we step up dc power using transformer?
we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx
sir can you operated Transformer on frequency from that for which is design?
after parallaing two generators current is shooting up in both the generators.for ex: load is 400 kw..after paralling and load sharing current in running gen is approx 900 amps and incoming is 750 amps which is too high when trying toshift the load current in incoming gen is coming more than 1300 amps and both getting tripped and making blackout..
Why we are not placing c.B 's btwn generator and transformer.? what happens when generator gets disconnected from transformer when it is running @ full load?
how can we measure the import power and export power in the same line?
Why electricity in India is in the multiples of 11 like 11kv, 22kv, 33kv
power inverter we are using 2n3773 power transister in that places we can use any IGBT ?
what is the difference between direct loading and indirect loading?
tell me about roaster switch .& what is the function in transmission & distribution?
