Question

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?

Answer 1

The induced voltage in the Secondary is 18 volt.

Step-by-step 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

`(V_(p))/(V_(s))=(N_(p))/(N_(s))`

Where,
`N_(p)` = Number of primary coil

`N_(s)` = Number of secondary coil

`V_(p)` = Voltage of primary coil

`V_(p)` = Voltage of primary coil

Put the value into the formula

`(120)/(V_(s))=(500)/(75)`

`V_(s)=(120*75)/(500)`

`V_(s)=18\ Volt`

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