1. A 200/5 ampere current transformer is connected (to a 0-5 ampere meter) to read the line current of a feeder. The meter reads 2 1/2 amperes. The current in the feeder is..............a) 200amps b) 100amps c) 40amps d) 5amps.

Thank you

 

How much current do YOU think it is, and how did you arrive at that answer?

Show how you worked the problem.

 

This was a multi choice... wasnt certain of the answer.

 

Have you ever heard the term "RATIO"?

 

200A will translate into 5A. So if you are reading 2,5A instead of 5A then...
