In household electric ovens, the heating element has only two settings—on and off. A thermostat connected to the oven’ s temperature knob is the only control on temperature, automatically switching the element off when the indicated temperature is reached, which happens quickly in modern ovens, and subsequently on or off as needed to maintain temperature. Which of the following statements is most strongly supported by the information above?
选项
A、Because in each case the heating element alternates between on and off, a modern household electric oven uses little more power at its maximum temperature setting than it does at its lowest temperature setting.
B、Once the indicated temperature has been reached and is being maintained by the thermostat, the heating element will be switched off for a greater proportion of the time than it is switched on.
C、The accuracy with which household electric ovens maintain their temperature could not be improved on by ovens whose heating elements have more than two settings.
D、In a correctly functioning modern household electric oven, the thermostat will generally not switch the heating element off when the oven’ s temperature is more than a few degrees above the indicated temperature.
E、If the thermostat of a modern household electric oven is disabled so that the heating element remains switched on, the oven’s temperature can eventually become higher than the maximum temperature setting on its temperature knob.
