∙ 14y agoTo find the amps when watts and voltage are known, you can use the formula: Amps = Watts / Volts. Simply divide the power in watts by the voltage to get the amperage.
To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
To convert amps to watts, you also need the voltage. The formula to calculate power in watts is Watts = Amps x Volts. If the voltage is 120V, then 37.5A would be equivalent to 4500W (37.5A x 120V = 4500W).
watts = amps (times) voltage watts (divided by) voltage = amps 140 (div by) 120 = 1.66 140 (div by) 125 = 1.12
Using the equation Volts X Amps = Watts, you can take 3000 watts / Volts to get your answer: 3000W/240V = 12.5A or 3000W/120V = 25A So, at 240 volts you will use 12.5 amps for 3000 watts of power. Or at 120 volts you will use 25 watts.
To calculate watts, you can multiply the amperage by the voltage (Watts = Amps x Volts). If we assume a standard voltage of 120 volts in a household circuit, then 10 amps would be equal to 1200 watts (10 amps x 120 volts).
To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
You just have to divide the watts by the voltage to find the amps. For example 60 watts on a 120 v system would take ½ amp.
To find the power in watts, multiply the current (5.0 amps) by the voltage (which is needed to provide the full power calculation). Without voltage information, we can't determine the power in watts solely from current (amps).
None or a million, it depends on the voltage. Multiply the amps by the volts to find the watts.

The formula you are looking for is I = W/E. As you can see the voltage has to be known to answer the question.
AC power is electricially, a value that is expressed in watts and voltage is the electromotive force that combined with amps, makes up the formula to find watts. Watts is the product of Amps x Volts. W = amps x volts.
