(Ns/Np)=(Vs/Vp)⇒ (200/100)=(Vs/120)⇒ Vs=240 V also (Vs/Vp)=(ip/is)⇒ (240/120)=(10/is)⇒ is=5 A

Q. The primary winding of a transformer has $100 t u r n s$ and its secondary winding has $200 t u r n s$ . The primary winding is connected to an AC supply of $120 V$ and the current flowing in it is $10 A$ . The voltage and the current in the secondary winding is

$240 V, 5 A$

$240 V, 10 A$

$60 V, 20 A$

$120 V, 20 A$

$\frac{N _{s}}{N _{p}} = \frac{V _{s}}{V _{p}} \Rightarrow \frac{200}{100} = \frac{V _{s}}{120} \Rightarrow V_{s} = 240 V$
also $\frac{V _{s}}{V _{p}} = \frac{i _{p}}{i _{s}} \Rightarrow \frac{240}{120} = \frac{10}{i _{s}} \Rightarrow i_{s} = 5 A$
