There is no direct relationship between watts and volts. Watts = volts x current in amps.
30 amps at 12 volts is equal to 360 watts (P = V x I).
To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.
30X240=7200
41.666 amps. Divide watts by volts.
The formula to calculate the relationship between amps, volts and watts is Volts X Amps = Watts or Volts = Watts / Amps or Amps = Watts / Volts therefore; 200 Watts divided by 1.95 Amps is 102.5641 Volts.
30 amps at 12 volts is equal to 360 watts (P = V x I).
volts times amps = watts
30 amps at 120 volts is 3600 watts. 30 amps at 240 volts is 7200 watts.
Watts and Volts are two distinct types of measurement.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
To answer this question a voltage must be given. Watts = Amps x Volts. <<>> Answer At 115 volts ac, 30 amps equals 3,450 watts.
Zero. Watts is the product of Amps x Volts. As you can see an amperage value is needed. Voltage = Watts/Amps. Volts = 200/? 20 volts
4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
30X240=7200
There is no way to tell, you don't have enough information. Watts are what you get by multiplying the amps x the voltage. Simply put, Volts X Amps = Watts.
Assuming you mean 12 volts, then you cannot run any 78 Amp fans. Unless your fans run at 0.38 volts, there is no way to draw 78 amps from 30 watts.
The formula you are looking for is W = I x E, Watts = Amps x Volts.
