Consider a step-up transformer (the output voltage is greater than the input voltage). What happens to the current in the output side compared to the input side?

What will be an ideal response?


As was discussed in the answer to question 26, the output current would be less
than the input current in order to maintain the same magnetic field in the piece of iron (the
iron core) in the transformer. Alternatively, we noted in this chapter that
(VI)output = (VI)input.
Therefore, an increased output voltage (compared to the input voltage) means a reduced
output current (compared to the input current) in order to keep the product the same.
