Variac calculations
Just a simple question that I am not sure about the answers:
I got a 900VA 220Volt Variac (TM) connected to the primary of a 1kVA , 45-0-45 toroidal (220:45-0-45) How much current will I draw at the various stages when I get 16-0-16 on toroidal sec. 1)Variac Prim. 2)Variac Sec. 3)Toroidal Prim - I would think must be same as Variac. Sec 4) Toroidal Sec. Thanx for any assistance.
