The ima of a transformer is the ratio of the number of primary winding turns to the number of secondary winding turns. In an ideal transformer, the power in the primary winding is equal to the power in the secondary winding. This means that the current in the secondary winding is inversely proportional to the number of secondary winding turns.

Therefore, if the number of secondary winding turns is greater than the number of primary winding turns, the current in the secondary winding will be less than the current in the primary winding. This means that the ima of the transformer will be less than 1.
