It depends on the load's resistance (ohms). By using the formula P (watts) = V^2 (volts) / R (ohms), and assuming a load resistance of 1 ohm, the voltage would be 1 volt for 1 watt.
The voltage delivering 1 watt depends on how many amps are present. We use watts to measure power (P), and amps (I) times volts (E) equals watts. We sometimes see the equation P = I x E written to express this relationship. Let's look at a couple of instances. If we have 1 amp times 1 volt, we'll get 1 watt. But 1/2 amp times 2 volts also equals 1 watt. Likewise, 10 amps times 0.1 volts equals 1 watt. Or 0.001 amps times 1,000 volts (1 milliamp times 1 kilovolt) equals 1 watt. As you can see, it is a combination of voltage and current that gives us wattage (power), and any voltage you can imagine can be used to get one watt of power when you have the correct current (amperage).
There are zero amps in a watt. I = W/E. W = A x V. It depends on how many volts there are. Since watts is amps times volts, amps is watts divided by volts. If you had a 120V circuit with 1 watt, there would be 1/120, or 0.00833 amps flowing in that circuit Note: This is the resistive answer, with a power factor of 1. For reactive loads, things change, but the basic question is answered.
Answer: Volts x Amps = Watts This question lacks sufficient information for an answer. It isnt. One watt is equal to one Joule of energy per second. Amperage is current, or to state it more accurately, the amount of electrons passing through a point in a second.
Power = Voltage x Current, so Current = Power / Voltage. {1 amp = (1 watt)/(1volt)}. At 120 Volts, then Current = (13 watts)/(120 volts) = 0.10833 amps.But at 12 volts, (13 watts)/(12 volts)= 1.0833 amps.
You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.
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.)

The watt is a measurement of work done by an object at constant velocity and under constant force. 1 watt, therefore, is equal to 1 Joule per second.
Unfortunately, the question as phrased is meaningless. A watt or kilowatt is a measure of voltage times current - one kilovolt at one amp of current dissipates one kilowatt of energy, but the same kilovolt at one tenth of an amp of current only dissipates 100 watts. Here's the formula: Watts = Volts * Amps
Watts = Volts x Amps x Power Factor. An incandescent light bulb is a resistive load so PF = 1. ANSWER: = 1/2 Amp
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
1 million electron-volts = roughly 4.45 watt-hours.By definition, 1 electron-volt is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electric potential difference of one volt.The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time.

Power = volts x amps, so your example will be 12 x 0.5 = 6 watts. (500mA = 0.5 amp) Note we don't talk of 'watts per hour', it is just watts. 1 watt = 1 joule per second
The SI unit of power, the watt, is named after James Watt, for his contributions to the development of the steam engine. The symbol for watts is a capital W. The watt is a derived unit, equal to 1 joule of energy per second, a rate of conversion of energy. In electricity, 1 watt is 1 ampere at 1 volt (watts = amps X volts).
