What is the voltage output (in V) of a transformer used for rechargeable flashlight batteries, if its primary has 475 turns, its secondary 8 turns, and the input voltage is 114 V

Answer :

Answer:

Output voltage is 1.92 volts.

Explanation:

Given that,

Number of turns in primary coil, [tex]N_p=475[/tex]

Number of turns in secondary coil, [tex]N_s=8[/tex]

Input voltage, [tex]V_i=114\ V[/tex]

We need to find the voltage output of a transformer used for rechargeable flashlight batteries. For a transformer, the number of turns and the voltage ratio is given by :

[tex]\dfrac{N_p}{N_s}=\dfrac{V_i}{V_o}\\\\\\V_o=114\cdot\dfrac{8}{475}\\\\V_o=1.92\ V[/tex]

So, the output voltage is 1.92 volts.
