An auto-transformer is rated for a small step-up to high voltage. If its primary voltage is 100V and the secondary tap is at 150V, what concerns might arise if the auto-transformer is used in residential applications?
💡 Hint: Think about the implications of a high voltage reaching low-voltage appliances.
If an auto-transformer's primary aims to step down 480V to 240V, what effects would dramatically increasing the voltage to 720V have on its operation?
💡 Hint: Consider the relationship between voltage and magnetic properties of transformers.
