Marks: +1, -0

The current transformer that is used to measure a 100 A current by 5 A ammeter is a ____

Solution:

100 A current is measured by 5A ammeter with the use of current transformer.

I_1/I_2=V_1/V_2=N_1/N_2

So secondary turn is 100 and primary turn is 5 then it can be measured by step up transformer.
