A step-down transformer is connected to ...

A step-down transformer is connected to `2400` volts line and `80` amperes of current is found to flow in output load. The ratio of the turns in primary and secondary coil is `20:1.` if transformer efficiency is `100%`, then the current flowing in primary coil will be

`15A`

`50A`

`25A`

12.5A`

Text Solution

Verified by Experts

The correct Answer is:

`(N_(s))/(N_(p))=(i_(p))/(i_(s))or (25)/(1)=(i_(p))/(2)impliesi_(p)=50A`
