The effect on the primary current if the secondary coil is short circuited.

Explanation of Solution
Introduction:
A transformer is a device used to step up or step down the voltage. It works on the principle of
If the secondary coil of a transformer is shorted, the current in the secondary coil will be direct which will oppose the change of flux in the primary coil, resulting in a much smaller flux and voltage induced in the primary coil. As a result, the difference between the external voltage and the voltage which is induced is much larger, and so is the primary current.
Conclusion:
If the secondary coil of a transformer is shorted, the difference between the external voltage and the voltage which is induced is much larger, and so is the primary current.
