Question

Also, make it one sentence and like a 9th grader. Thank you.

Answer 1

To calculate the efficiency of a toaster, divide the useful heat energy it produces (like the toast) by the total electrical energy it consumes, then multiply by 100 to get a percentage. In simple terms, it shows how well the toaster turns electricity into heat for making toast.
