Most appliances supply volts and amps figures only. I know there's a formula for determining watts by multiplying volts X amps, but multiplying any figure X 110 volts doesn't seem to work. Anyone know what I'm doing wrong with this?
The tag on the appliance usually has the voltage number for it. You may see 110, 115, or most usually now, 120 volts.
You can take:
Watts = volts (120) X amps
Here is an example using the tag for the electric heating element on a Suburban water heater. As you can see it is rated for 120 volts.
1440 watts = 120 volts X 12 amps
