One volt is zero watts.
Five amps is 600 watts on 120 v and 1200 watts on 240 v.
As watts equals volts times amps (ohms law simplified) you are missing part of the equation.. Let's say you are asking about how many watts is 1 amps at 12v then... If W = V x A then 1A at 12v = 12 watts
100v at 1A is 100 watts, 240 v 5A is 1200 watts. The other numbers give intermediate amounts of watts.
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.

100v at 1A is 100 watts, 240 v 5A is 1200 watts. The other numbers give intermediate amounts of watts.
The formula you are looking for is W = A x V.
8,000 watts = 8 kVA / (the power factor) If the power factor is 1, then 8 kVa = 8,000 watts.
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
P = V*I, and V = I * R, so: P = V^2 / R: P = 16/30 = ~.5 watts.
There are 1/.1 = 10, .1 watts in 1 watt.
50 watts for a small one, 200 watts for a big one. The voltage is 230 v in Europe, 120 v in USA.
according to google calculator "1 hp in watts": 1 hp = 745.699872 watts

Watts (P) = Volts (V) x Current (I) Assumption V = 115 VAC, I = 1A P= 115 x 1, P = 115W 1 Amp @ 115VAC power system = 115W Assumption V =230VAC (international system), I =1A P = 230 x 1, P = 230W 1 Amp @ 230VAC power system = 230W
