Consider a transformer used to recharge rechargeable flashlight batteries, that has 500 turns in its primary coil, 4 turns in its secondary coil, and an input voltage of 120 v. what is the voltage output in volts, of the transformer used for to charge the batteries?

Output Voltage = 0.96 volts

Explanation:

As we know by the equation of transformer we have

here we know that

= voltage of primary coil = 120 Volts

= voltage of secondary coil

= number of turns in primary coil = 500

= number of turns in secondary coil = 4

now we will have
