What are the differences between 120 volt and 240 volt electrical systems?

The main difference between 120 volt and 240 volt electrical systems is the amount of voltage they provide. A 120 volt system is commonly used for household appliances and lighting, while a 240 volt system is typically used for larger appliances like stoves and dryers. The higher voltage of a 240 volt system allows for more power to be delivered, making it suitable for heavier electrical loads.

What are the differences between 240 volt and 120 volt electrical systems and how do these differences impact the efficiency of household appliances?

The main difference between 240-volt and 120-volt electrical systems is the amount of voltage they provide. 240-volt systems deliver more power than 120-volt systems, allowing appliances to operate more efficiently. Household appliances that require higher power, like ovens and dryers, typically use 240-volt systems for better performance.
