Question { 11139 }

define main transformer?

Answer

If a load is connected to the secondary, an electric
current will flow in the secondary winding and electrical
energy will be transferred from the primary circuit through
the transformer to the load. In an ideal transformer, the
induced voltage in the secondary winding (VS) is in
proportion to the primary voltage (VP), and is given by the
ratio of the number of turns in the secondary (NS) to the
number of turns in the primary
