If the efficiency of a transformer is 100%, which of the following equations would be correct?
A
N\(_p\)E\(_p\) = N\(_s\)E\(_s\)
B
N\(_s\)I\(_p\)= N\(_p\)I\(_s\)
C
N\(_s\)I\(_s\) = N\(_p\)I\(_p\)
D
I\(_p\)E\(_s\) = I\(_s\)E\(_p\)
Verified Correct Answer: D.
Physical Principles & Numerical Solution
For a transformer with 100% efficiency, the input power equals the output power:
E\(_p\)I\(_p\) = E\(_s\)I\(_s\)
