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

18 volt

Step-by-step explanation:

We have given number of turns in primary
`N_1=500`

Primary voltage
`V_1=120volt`

Number of turns in secondary
`N_2=75`

For the transformer we know that
`(N_1)/(N_2)=(V_1)/(V_2)`

So
`(500)/(75)=(120)/(V_2)`

`V_2=18\ volt`

So the induced voltage across secondary is 18 volt
