What is true sine wave or pure sine wave inverter?? Is it sine wave or step wave?? If it is step wave, waves with how much step is considered as pure sine wave? Is it possible to produce pure sinewave using power electronics?
y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
