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?

Respuesta :

Answer:

Output Voltage = 0.96 volts

Explanation:

As we know by the equation of transformer we have

[tex]\frac{V_1}{V_2} = \frac{N_1}{N_2}[/tex]

here we know that

[tex]V_1[/tex] = voltage of primary coil = 120 Volts

[tex]V_2[/tex] = voltage of secondary coil

[tex]N_1[/tex] = number of turns in primary coil = 500

[tex]N_2[/tex] = number of turns in secondary coil = 4

now we will have

[tex]\frac{120}{V} = \frac{500}{4}[/tex]

[tex]V = 0.96 Volts[/tex]
