So what is power/time? (ie:watt-hour)

[–] [email protected] 6 points 4 weeks ago (1 children)

Notice the absence of division. It's not watts per hour, but watt(s times)hours. So power multiplied by time which is energy. Just like the video explains.

Watts are analogous to velocity, so if you were to divide watts by time, the result would be the increase of power i.e. acceleration of energy consumption.

I think @[email protected] heard "energy is power over time", which is correct, but in the duration meaning of "over", not the division one. English is confusing sometimes!
