How many volts are in Watts?

Using Ohms law, you would multiply amperage times volts to get watts. For instance a 12 volt circuit drawing 2 amps would consume 24 watts of power (12*2=24). A 60 watt light bulb powered by 120 volts in a house would draw .5 amp of current (60/120= .5).

How many amps does a 100 watt bulb?

For example 1 amp * 110 volts = 110 watts.
Converting Watts to Volts.
The conversion of Watts to Volts at fixed amperage is governed by the equation Volts = Watts/Amps.
For example 100 watts/10 amps = 10 volts.

How many watts is 20 volts?

Voltage * Amperage = Wattage.
So if you have a laptop that has 20 volt 4.5 amp printed on the power supply then that power supply is capable of using 90 watts. 20 volts * 4.5 amps = 90 watts.
