It's a meaningless question if the person answering it simply doesn't have some qualitative frame of reference to gain intuition from...and gaining intuition on EM phenomena grounded in reality isn't easy; there'd be a lot more EEs and physicists out there otherwise.
Besides, if you're walking into a time-constrained exam of toy questions, I fail to see what incentive a student may have to corroborate toy answers against a reality that it may or may not be an approximation of.
- skissane 7y agoA lot of household appliances have power measured in watts (microwave ovens, electric heaters, etc). And megawatts and gigawatts are commonly used in discussion of electric power plants. My electricity bill is in kilowatt-hours, and that's what my electricity meter says on the front as well. Isn't that enough background knowledge to guess that an electric car would likely be more than a kilowatt (my microwave oven is more than that) but less than a gigawatt (a decent sized power station?)
