Q1.Show that in an ideal transformer when the voltage is stepped up by certain factor the current get stepped down by the same factor.
Hello,
We know that for ideal transformer power is constant that means
VI = constant =k
If V is increased 2V. Let corresponding change in current is I'.
Then 2V I' = k
=> 2V I' = VI
=> I' = I/2
Hence when the voltage is stepped up by certain factor the current get stepped down by the same factor.
