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

Answer:

Output Voltage = 0.96 volts

Explanation:

As we know by the equation of transformer we have

$\frac{V_1}{V_2} = \frac{N_1}{N_2}$

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

$\frac{120}{V} = \frac{500}{4}$

$V = 0.96 Volts$
