A transformer has 250 primary turns and 500 secondary turns. If 200 V electric potential is applied to the primary resulting in a current of 5 mA, find the secondary voltage and current.

Text Solution

Verified by Experts

`(n_(p))/(n_(s)) = (v_(p))/(v_(s))`
Power (input) = power (output)
`i_(p)v_(p) = i_(s)v_(s)`
`(v_(p))/(v_(s)) = (i_(s))/(i_(p))`
