What is a key difference between gas ranges and electric ranges?

1. Gas ranges require less voltage

2. Electric ranges require a 240-volt electrical supply

3. Gas ranges have electronic controls

4. Electric ranges are more energy-efficient

The correct answer is: Electric ranges require a 240-volt electrical supply

The distinction that electric ranges typically require a 240-volt electrical supply is a fundamental characteristic of these appliances. This higher voltage enables electric ranges to generate the necessary heat quickly and efficiently to cook food. In residential settings, most standard electrical outlets supply 120 volts, which is insufficient for the high-demand heat needed for cooking on electric ranges. This is why electric ranges often accompany dedicated circuits rated for 240 volts to ensure optimal performance. In contrast, gas ranges utilize natural gas or propane as their primary energy source for cooking, which enables them to operate independently of the electrical supply for heat generation. Therefore, while they may require electricity for features like ignitors or electronic controls, their primary function does not depend on higher voltage electrical supplies. Understanding this difference is important for both safety and performance considerations during installation and use of these appliances.
