A typical wall outlet voltage in the United States is 120 volts. Personal MP3 players require much smaller voltages, typically 292.2 mV . If the number of turns in the primary coil is 2464 , calculate the number of turns on the secondary coil of the adapter transformer.

The secondary coil should have 6 turns

Step-by-step explanation:

Voltage Transformer

Voltage step-down transformers reduce the voltage of a higher voltage circuit to a lower voltage circuit for the load voltage requirements.

The turns ratio is the division of the number of turns in the primary coil Np by the number of turns in the secondary coil Ns by the equation

This ratio should also equal the voltage of the primary side Vp divided by the voltage of the secondary side Vs, as given by

Thus, we have

Solving for Ns

The secondary coil should have 6 turns

the answer is:

mean: 6

mad: 2.14
