Using a regular house hold plug for power.

I'd like to know whether i could calculate how many watts used if I only know 110 V and the power is from a household circuit. Is it possible? If it is, how do i calculate it?

I don't think you can do that. you need the number of amps and the power factor for that device.

I don't understand u question but the formula is Watts= V * I
watts = 110 * 10
watts=

Watts is a unit of power (energy per second).
If you use the item for 28 seconds, you'll get an amount of energy.

watts = A*V*PF
I don't think you can get it with just the Volts. amps*volts*power factor (which is resistance).
ohms laws...but laws are made to be broken.

no, you also need to know the amperage
