That depends on the voltage. One amp flowing at a potential of 1 volt produces 1 watt of power (equal to an energy consumption of 1 joule per second). 4 amps flowing at a voltage of 250 volts produces a kilowatt of power. This would be enough to satisfy the individual needs of a lot of the electrical equipment around the house.

How many milliamps equal one watt?
It depends on the voltage. watts = amps x volts So if the potential difference (another way of saying voltage) was 1V, then a current of 1 Amp, or 1000 milliamps, would result in a power of 1 watt.
How many amps does a 5 watt 12 volt bulb draw?
1/2 amp.
How many amps would a 150 watt bulb draw in a 120v circuit?
1 amp
How much amperage is there in 18000 kilo watt?
There are zero amps in 18000 kilowatts. A watt is the produce of amps times volts. With out a voltage stated the calculation can not be made. When the voltage is stated, the following equation should be used, I = W/E. Amps = Watts/Volts. Remember 1000 watts is equal to 1 kW.
How many milliwatts equal 1 watt?
1 KW = 1000 Watts.......1 mW = .001 Watt.......1 microwatt or uW = .000001 Watt
One watt is equal to how many voltage?
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.
How many amps are in 40 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
How amps needed to supply 1950 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
How many amps does a 60 watt light use?
About 1/2 amp.

What does James watt have to do with calculating power?
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).
How many volts are equal to one 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).
How many unit is 1 kv?
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
