Question

8. The number of turns in the primary of a transformer is two times greater than that in the secondary, then

a)identify the type of transformer?

b) If 50V is given to the primary, What will be the voltage obtained in the secondary?

c)If the current in its primary coil is 4A What will be the current in the secondary?​

Answer 1

Explanation:

a = step down transformer

b= vs/vp=Ns/Np

vs/50= 1/2

vs= 50/2=25 V

c= vs/vp=.Ip/Is

25/50= 4/is

Is = 50×4/25=200/25=8A
