Question

A transformer consists of a 500 turn primary coil and a 2000-turnsecondary coil. If the current in the secondary is 3.0A, what isthe current in the primary?and WHy?

Answer 1

The correct solution will be "12.0 A".

Step-by-step explanation:

The given values are:

`N_p= 500 \ turn`

`N_s= 200 \ turn`

`I_s= 3.0 \ A`

By using the transformer formula, we get

⇒
`(N_p)/(N_s) =(I_s)/(I_p)`

⇒
`I_p = I_s* (N_s)/(N_p)`

On substituting the given values, we get

⇒
`=3.0 \ A* (2000)/(500)`

⇒
`=12.0 \ A`
