Question

How many turns are required to be wound in the secondary coil if the primary coil consists of 2000 turns with 22 AWG copper wire? Input Voltage = 220V, Input Current = 1A. The transformer is expected to work with 90% efficiency & expected to get 12V 5A output.

Answer 1

The number of turns required in the secondary coil is 109.

Step-by-step explanation:

In order to calculate the number of turns required in the secondary coil, we can use the turns ratio formula:

Ns/Np = Vs/Vp

Where Ns is the number of turns in the secondary coil, Np is the number of turns in the primary coil, Vs is the output voltage, and Vp is the input voltage.

Since we are given that the primary coil consists of 2000 turns and the input voltage is 220V, and we want to achieve an output voltage of 12V, we can rearrange the formula to solve for Ns:

Ns = (Vs/Vp) * Np

Plugging in the given values, we have:

Ns = (12/220) * 2000 = 109 turns

Therefore, 109 turns are required in the secondary coil.
