Final answer:
The power consumption of the microwave oven is 1000 W at any moment it is turned on, including for a period of 30 seconds. Energy consumption, which is different from power, would only vary based on how long it is on, but this question is solely about power consumption.
Step-by-step explanation:
When considering how much energy a device consumes, we differentiate between power consumption and energy consumption. The power consumption of a device represents how much electrical power the device requires to operate. The question asks the power consumption of your microwave oven that consumes 1000 W of electrical power when it's turned on for 30 seconds.
In this case, since the power rating of the microwave oven is 1000 W, it means that while the microwave is on, regardless of the duration, it will consume power at this constant rate. Therefore, the power consumption over any period of time the microwave is active, including 30 seconds, remains at 1000 W.
Energy consumption, however, would vary depending on how long the microwave is on. For instance, the energy used by the microwave in 30 seconds can be calculated by multiplying the power consumption (in watts) by the amount of time it is on (in seconds), giving you the total energy in joules.
