If you had an oven rated at 240 volts and only had a 208 volt supply available, what type of transformer would you use to raise the voltage?

The appropriate choice for raising the voltage from a 208 volt supply to meet the requirements of a 240 volt oven is a step-up transformer.

A step-up transformer is specifically designed for this purpose; it increases the primary voltage to a higher secondary voltage. By stepping up the voltage, it can effectively convert the lower supply voltage to the required higher voltage for the oven. In this scenario, the step-up transformer takes the 208 volts and transforms it to 240 volts, making it suitable for the oven's operation.

Although the term "buck and boost transformer" is commonly used, it specifically refers to transformers that can either raise (boost) or lower (buck) voltage levels depending on the requirements. While a buck and boost transformer can perform the necessary voltage adjustment, in this case, a straightforward step-up transformer suffices for the task of only increasing the voltage from 208 volts to 240 volts.

The other options, such as isolation transformers and standard transformers, serve different purposes in electrical applications. An isolation transformer provides electrical isolation between circuits without necessarily changing the voltage level, while a standard transformer typically does not specifically denote a function for stepping up or down voltage levels. Thus, the clarity of function with a step-up transformer makes it the
