Final answer:
To understand energy consumption in appliances, use the P = IV model and multiply power rating by usage time. Appliances like toasters have higher ratings due to greater energy needs.
Explanation:
In understanding the energy consumption of various appliances in your home using an energy consumption tracking app, you can utilize the model P = IV, where P represents power, I is the current, and V is the voltage. By multiplying the power rating of an appliance by the time it is used in hours, you can calculate the energy consumed. Appliances like a toaster have higher power ratings than a digital clock due to the amount of energy they require to function.
