How quickly does a 1kW appliance use energy?

948 views

Terrible with math and I barely understand the concepts but if my fridge is a 1kw fridge, how long of running it at its “maximum” would it take to use 8700kj(average adult recommendation)

Looking for the math to be explained too please.

kW = Kilowatt

Kilo = 1000
Watt = 1 Joule per second

So 1 kW means “1000 joules per second” or 1 kJ per second.

Therefore it would take 8700 seconds to use 8700 kJ.
