Final answer:
The required voltage to plug in a dryer or stove is 220 volts.
Step-by-step explanation:
The required voltage to plug in a dryer or stove is 220 volts (option a).
Stoves and dryers typically require higher voltage to operate efficiently. They are designed to handle the higher power demand of heating elements and motors. In the United States, the standard voltage for these appliances is 220 volts, which provides enough power for them to function properly.
For example, a stove might have heating elements that need high voltage to generate enough heat to cook food quickly and evenly. Similarly, a dryer may have a powerful motor that requires higher voltage to spin the drum and dry clothes effectively.
