In a transformer a 120 volt dc Primary of 500 turns is connected to a secondary of 75 turns. What is the Induced voltage in the Secondary?

Respuesta :

Answer:

18 volt

Explanation:

We have given number of turns in primary [tex]N_1=500[/tex]

Primary voltage [tex]V_1=120volt[/tex]

Number of turns in secondary [tex]N_2=75[/tex]

For the transformer we know that [tex]\frac{N_1}{N_2}=\frac{V_1}{V_2}[/tex]

So [tex]\frac{500}{75}=\frac{120}{V_2}[/tex]

[tex]V_2=18\ volt[/tex]

So the induced voltage across secondary is 18 volt
