900 amps is equal to how many watts?

Answer 1

In order to calculate wattage, you must know the value of the voltage source.

Using Ohms law, you can calculate wattage by multiplying the number of volts by the number of ampers (P=I X E), where P is the power in watts, I is the current in Amperes, and E is the source voltage in Volts.

So, at 240 volts, 100 amperes would represent 240V X 100A = 24,000 watts.

At 120 volts, 100 amperes would represent 120V X 100A = 12,000 watts.

At 12 volts, 100 amperes would represent 12V X 100A = 1200 watts.

Note: This is only completely true for DC (Direct Current) or 100% resistive AC loads. If you're calculating wattage on an inductive load (such as a large tranformer or fluorescent light fixture), for any given amount of current, the actual value for wattage will always be less than that calculated amount.

If you're unsure about the nature of an AC load, you can only use ohm's law as an approximation of wattage. For AC loads, you will often see the term "Volt-Amperes" used instead of "Watts" when calculating the power consumption of AC loads.

Answer 2

You cannot convert watts to amps, since watts are power and amps are coulombs per second (like converting gallons to miles). HOWEVER, if you have at least least two of the following three: amps, volts and watts then the missing one can be calculated. Since watts are amps multiplied by volts, there is a simple relationship between them.

However, In some engineering disciplines the volts are more or less fixed, for example in house wiring, automotive wiring, or telephone wiring. In these limited fields technicians often have charts that relate amps to watts and this has caused some confusion. What these charts should be titled is "conversion of amps to watts at a fixed voltage of 110 volts" or "conversion of watts to amps at 13.8 volts," etc.

85 watts equals zero amps.

Answer 3

To convert amps to watts, you need to know the voltage at which the current is flowing. The formula to calculate watts is watts = amps x volts. Without the voltage information, it is not possible to determine how many watts 900 amps is equal to.

Answer 4

In calculating watts, the formula is the same for AC or DC current -- W(Watts) = Volts (V) times Amps (A). Therefore, 12 Volts X 105 Amps = 1,260 Watts.

Answer 5

It depends on the voltage of the system. Once you determine the voltage, the formula to figure out the amperage is: Amps = Watts / Volts

Answer 6

That depends on circuit voltage.

1 watt is equal to 1 volt times 1 amp.
