At 120V, 120 watts make 1 amp. That means that 1 amp = 120 watts.

In short, 3 amps is 360 watts .
| Current (A) Voltage (V) Power (W) | 3 amps 120 volts 360 watts | 4 amps 120 volts 480 watts | 5 amps 120 volts 600 watts | 6 amps 120 volts 720 watts |

Using the W ÷ V = A variation of Ohm’s law, you can calculate that 1,500 watts ÷ 120 volts = 12.5 amps .
The formula to convert voltage to watts is watts = amps x volts.
Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts .
A typical lightning flash is about 300 million Volts and about 30,000 Amps. In comparison, household current is 120 Volts and 15 Amps. There is enough energy in a typical flash of lightning to light a 100-watt incandescent light bulb for about three months or the equivalent compact fluorescent bulb for about a year.

A 20-amp breaker can support up to 2,400 watts on a single circuit. The safe maximum for a 20-amp circuit is 1,920 watts , but circuits should not be loaded to more than 80 percent of their maximum capacity.
What does a Watt mean? The Wattage of the light is the amount of energy it takes to produce a certain amount of light. The higher the wattage, the brighter the light , but also the more power it uses.
If your lighting circuit at home is protected by a typical 5 amp fuse you can multiply this by the voltage to get 1150 Watts .
