The primary coil of an ideal transformer has 100 turns and its secondary coil has 400 turns. if the ac voltage applied to the primary coil is 120 v, what voltage is present in its secondary coil?

The formula used in calculations relating to transformers is:

Secondary voltage (Vs)/ Primary voItage (VP) = Secondary turns (nS)/ Primary turns (nP)

 

Substituting the given values to find for Vs,

Vs / 120 V = 400 turns / 100 turns

Vs = 480 V
