Transformers

Step 1: Use the transformer current equation.
For an ideal transformer, the ratio of the currents in the primary and secondary is inversely proportional to the ratio of the number of turns:

%5Cfrac%7BI_1%7D%7BI_2%7D%20%3D%20%5Cfrac%7BN_2%7D%7BN_1%7D

where

N_1

and

N_2

are the number of turns in the primary and secondary coils, respectively, and

I_1

and

I_2

are the currents in the primary and secondary coils.
Step 2: Calculate the secondary current.
Given the turn ratio is 4:1, the current in the secondary will be

1%20%5C%2C%20%5Ctext%7BA%7D

. Final Answer:

%5Cboxed%7B1%20%5C%2C%20%5Ctext%7BA%7D%7D
