Which outcome occurs when a step-down transformer is connected with reverse polarity in a low-voltage lighting circuit?

A)Transformer core saturation and overheating
B)Reduced voltage output on secondary winding
C)Short circuit protection activates immediately
D)Normal voltage transformation, no disruptions

💡 Explanation

Reversed polarity causes the magnetizing current to drastically increase, leading to Transformer core saturation. This occurs because increased current flow generates excessive core flux, therefore inducing significant eddy current losses and dramatic overheating, rather than a simple voltage reduction.
