In a stap-up transformer, if ratio of turns of primary to secondary is 1 : 10 and primary voltage is 230 V. If the load current is 2 A, then currect in primary is

A

20A

B

10A

C

2A

D

1A

Text Solution

Verified by Experts

(a) `(N_(P))/(N_(s))=(1)/(10)`
`V_(p)=230 V, I_(s)=2A`,
`(I_(P))/(I_(s))=(N_(s))/(N_(P))implies(I_(P))/(2)=(10)/(1) implies I_(P)=20A`
