How many ampere in 1000 watts with 220v?

Answer 1

The wattage on a light bulb really is based on normal usage in a houshold 120 voly outlet. They build it with the proper resistance in the filiment so that at 120 volt it consumes the labeled watts. a 75 wat bulb has about 144 ohms resistane so if you put in a 120v socket it uses 75 watts

the watt measures power being consumed

Amps is the current flowing

voltage is the force causing current to flow. The find the , you need to know some of the facts. For example: to calculate the watts; we need to know the voltage and the current and use the formula:

Power(watts)= current(amps) X volts

also Volts= current X Resistance(ohms)

In your question; assuming the bulb is consuming 100w and the voltage is 220, them 4.54 amps is flowing

I hope this helps The question says 1000W, not 100W.

Although 1000W filament lamps certainly exist, the huge majority are discharge lamps, for which much of the comment above is wrong or irrelevant.

The comment about filament resistance should also be qualified by the fact that it is that resistance only at white heat - running temperature. At room temperature it is almost a dead short.

It is also worth mentioning that current (amps) is not consumed, only energy is and energy is what (watt) you pay for.

Answer 2

220 volts is not 1 phase, its 3 phase. In North America 220 - 240 volts is single phase. Divide watts by volts to get amps, ohms law

Answer 3

light bulb is consider as resistive load. so, pf is 1 therefore current drawn by 1000 watt 208volts bulb is 4.8A

Answer 4

The formula you are looking for is I = W/E.

Answer 5

Divide 1000 by 220 = 4.5 amps
