Question

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?

Answer 1

Output Voltage = 0.96 volts

Step-by-step explanation:

As we know by the equation of transformer we have

`(V_1)/(V_2) = (N_1)/(N_2)`

here we know that

`V_1` = voltage of primary coil = 120 Volts

`V_2` = voltage of secondary coil

`N_1` = number of turns in primary coil = 500

`N_2` = number of turns in secondary coil = 4

now we will have

`(120)/(V) = (500)/(4)`

`V = 0.96 Volts`
