1.	The primary coil of an ideal stepup transformer has 100 turns and the transformer ratio is also 100. The input voltage and power are 220 V and 1100 W. Calculate (i) number of turns in secondary (ii) current in primary (iii) voltage across secondary (iv) current in secondary (v) power in secondary.
Answer» Here, `n_(P) = 100, K = 100, E_(P) = 220 V`, `P_(i) = 1100 W` (i) From `K = (n_(s))/(n_(P))` (ii) From `P_(i) = E_(P) I_(P)` `I_(P) = (P_(i))/(E_(P)) = (1100)/(250) = 5 A` `(E_(s))/(E_(p)) = (n_(s))/(n_(P)) = K` (iv) `(I_(s))/(I_(P)) = (n_(P))/(n_(s)) = (1)/(K)` `I_(s) = (I_(P))/(K) = (5)/(100) = 0.05 A` (v) Power in secondary `= P_(0) = P_(i) = 1100 W`
