It's 120 watts for most things that have a power factor of 1, but some things have a power factor less than 1, so more current is needed.
CFL lights have a power factor of about 0.6, TVs have a power factor about 0.8, for computers it's 0.6-0.7. These things don't use a lot of current so it does not matter too much.
If the power factor is less than 1, the power is the voltage times the current times the power factor.

The formula you are looking for is W = Amps x Volts. Transposed Amps = Watts/Volts.
What else can I help you with?
Can you have to many appliances plugged into your house?
In theory, as many as you want. However, the circuit supplying the receptacle(s) you are using has a maximum capacity before the circuit protective device opens (usually a fuse or circuit breaker). Since appliances come in many sizes / wattages, there is no single answer. Some large appliances require a dedicated circuit with only one single receptacle, so that other things can not be plugged in at the same time on that circuit. Conversely, a 15 amp general purpose circuit could probably handle 100 clocks. first determine how many amps the circuit is fused at. then how many watts the appliances use that are on the same circuit. then you take the watts divided by volts (120) = amps....add them up.
How many watts are deadly?
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
How many watts does it take to run a paper shredder?
A small shredder 100-200 watts.
Why does a wall switch 'crackle' and the light flicker?
There is a high current draw on the circuit and the switch is getting old. Change out the switch, see if you can find a 20 amp switch as the internal contacts are designed to take the higher amperage. Check how many lamps are in the circuit in watts, add them together and use the formula for amps. Amps = Watts/Volts (120).
How many watts can you plug into a 115 volt outlet?
A typical 15-amp, 115-volt residential outlet can handle up to 1,725 watts (115 volts * 15 amps). However, it's recommended to leave some margin and avoid continuously drawing the full capacity to prevent circuit overloading.
How many volts does it take to make 1 horsepower?
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
How many take amp 40 watt fluorescent lamp?
Watts= voltage times amps. So if you divide Watts by voltage, you will get amps = .33333 or about a 1/3 amp load. This is assuming a 120 volt circuit.
How many dc volts does it take to make 1 horsepower?
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts (Doesn't matter if the source is AC, DC, or a combination of both.)
How many watts does it take to equal twenty five horsepower?
18650 watts

How many watts does it take to equal ten horsepower?
A horsepower is equal to 746 watts, so 10 x 746 = 7,460 watts.
How many watts does it take to equal two horsepower?
Rule of thumb, 1 HP = 746 watts.
