which trsanmission is easy and cost effective AC or DC.
Answer Posted / anbuselvan
Both AC and DC has its own Merits and demerits.
But Based on Installation,Maintenance and Efficiency, DC is
best than AC.
Bcaz, in AC has Many Trans Losses,Its required much copper
or Alumin for each line.But in case of DC need not to have
much copper, lesser Trans Losses.
In DC its required Converter and Inverter with heavy
rating.but nowdays its very popular and working more
effective and efficiently.therefore the conversion process
is not much complicated.
In Electrical engineering, our main objective is to transfer
the Power with high efficiency(i,e.,Min loss).
So Upto my knowledge DC is better than AC.
Thank you
