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:

The induced voltage in the Secondary is 18 volt.

Explanation:

Given that,

Voltage = 120 volt

Number of turns in primary = 500

Number of turns in secondary = 75

We need to calculate the induced voltage in the Secondary

Using relation number of turns and voltage in primary and secondary

[tex]\dfrac{V_{p}}{V_{s}}=\dfrac{N_{p}}{N_{s}}[/tex]

Where, [tex]N_{p}[/tex] = Number of primary coil

[tex]N_{s}[/tex] = Number of  secondary  coil

[tex]V_{p}[/tex] = Voltage of primary coil

[tex]V_{p}[/tex] = Voltage of primary coil

Put the value into the formula

[tex]\dfrac{120}{V_{s}}=\dfrac{500}{75}[/tex]

[tex]V_{s}=\dfrac{120\times75}{500}[/tex]

[tex]V_{s}=18\ Volt[/tex]

Hence, The induced voltage in the Secondary is 18 volt.
