Hi, for a physics project we have to find the power usage of household appliances.
My charger says "60W inputAC 100-240V 1.5A output 16.5-3.65V"
Would the watts just be 60W? Or would I have to calculate the amount by using P=AMPsx120volts (provided by my teacher)?
My other charger says "input 100-240V output 5.1V=850mA 0.2A"
How would I calculate the amount of watts for this charger?
Would I use P=AMPxvolts?
I'm not sure what number to use for the volts and AMPs because it lists a few numbers (as I stated above)
Thanks!
