It is not possible to answer this question as there is not enough information. The numbers of watts is a measure of the amount of energy being "used" per second. e.g. If a light bulb is rated at 100 watts this means 100 joules of energy are being "used" per second by the bulb. To be able to calculate the number of watts in 7400 volts we also need the current, which is measured in amps. Amps are a measure of the amount charge flowing around an electrical circuit per second. e.g. 13 amps means 13 coulombs of charge are flowing round the circuit per second. A volt can be though of at "the amount of energy in each coulomb" - although this is not the definition a physacist would give you! So multiplying volts and amps will give the number of watts. For example, if your 7400 volts are causing a current of 13 amps to flow, then the power will be: 7400 x 13 = 96200 watts (or 96.2 kW).
Another Answer
Your question is equivalent to asking 'How many kilometres per hour is 20 metres?'
There are zero watts in 700 volts.
1KW is 1000w. one watt is equals to product of volt and current. current=watt/volt =1000/240 =4.1667 amps
If it is an 18 watt 12 volt bulb, then yes. But an 18 watt 120 volt bulb - then no.
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
ummm...4(?) is this a trick question?
1/2 amp.
Probably about 180 watts, assuming 90% efficiency.
It will power two 400 watt lamps.
There is no volt meter or amp meter in a DC watt meter.
1KW is 1000w. one watt is equals to product of volt and current. current=watt/volt =1000/240 =4.1667 amps

Electricity is not sold by the volt. It is sold by the watt, a unit of power. One watt equals one volt-ampere.
calculation for Watts is = volts X amps P=IE P= Power(WATTS) I = Current(AMPS) and E = Voltage(VOLTS). So: I = P/E and E = P/I therefore: 1 watt = 1 ampere x 1 volt If you havea 240 volt lamp that is drawing .5 amp then it is using 120 Watts
This question does is not answerable. A watt is a volt times an amp. With out knowing how many amps the bulbs use there is no answer.
If it is an 18 watt 12 volt bulb, then yes. But an 18 watt 120 volt bulb - then no.
A watt is the product of amperage times voltage.
Per hour the answer is 400 watt-hours or 0.4 kW-hours (or units).
Ampire. watt/volt
