Put simply, kW refers to how much energy a device needs to work and kWh represents how much energy has actually been used. A power rating is the amount of electrical power needed for an appliance to work at any given moment. Energy is what is needed to keep the power going. So to ke...
To do so, you need to know how much power a device draws when plugged in. The average smartphone, for example, uses a 5w (or 0.005kw) charger. It takes three hours to charge fully. So, 0.005 (kw) x 3 (hrs) = 0.015 (kWh). You then multiply your kWh figure by your unit rate ...
