55) The primary coil of an ideal transformer has 600 turns and its secondary coil has 150 turns. If the current in the primary coil is 2 A, what is the current in its secondary coil

The current in its secondary coil is 8 A.

Explanation:

Given;

number of turns in the primary coil, = 600 turns

number of turns in the secondary coil, = 150 turns

current in the primary coil, = 2 A

current in the secondary coil, = ?

For an Ideal transformer, the emf in the primary winding is equal to the emf in the secondary winding.

The current in the secondary coil, can be calculated by applying turn ratio;

Therefore, the current in its secondary coil is 8 A.
