In a step-up transformer, the primary current is more than the secondary current. Explain. why?

Explanation

In any transformer the power in the primary = power in the secondary.
i.e., `V_(1)I_(1)=V_(2)I_(2)`
In the step-up transformer the primary voltage is less than the secondary voltage. To maintain the power as constant the primary current in a step-up transformer is more than the secondary current.
