The formula you are looking for is I =W/E. Amps = Watts/Volts.
To find the amperage, you can use the formula: Amps = Watts / Volts. In this case, with 72 Watts and 12 Volts, you would have 6 amps of current.
For a resistive load Watts = Volta * Amps. Therefore, you have 1/4 amp or 250 Milliamps (250ma)
You need the formula: Amps * Volts = Watts But you get to do the math.
W = A x V. Watts = Amps x Volts. There is not a voltage stated to multiply the 6 amps with so an answer can not be given.
That depends on the voltage, but the residential standard is 240 volt. At that voltage you sit at around 15 amps, however it MUST be on a 20 amp circuit for national (US) or Canadian electrical code, as you can only load your circuit to 80% of it's capacity.
Volts = Amps x Resistance Therefore Amps = Volts / Resistance
Watts and Volts are different units. It is like asking how many apples are there in 6 oranges. Watts = Volts x Amps x Power Factor Power Factor ranges from zero to one.
To answer this question the voltage must be known. Watts = Amps x Volts.
None by itself. Watts are measurement of power, and power is volts times amperes. Secondly, the 6 volts must be in an electrical circuit (loop) to create current flow (Amps). Thirdly, the resistance of whatever the 6 volts is powering determines current flow (Amps). So, without knowing the current flow, you cannot calculate power. Fourth, power (Watts, horsepower, ergs, chevals vapeur, etc) is a measurement taken over a certain time - it is not instantly measureable with an inexpensive meter like a voltmeter or an ammeter (Amp-meter).
This depends on the voltage ... amps = watts / volts 660 W / 110 V = 6 amps 660 W / 220 V = 3 amps 660 W / 330 KV = 2 mA
The formula is P = E x I. Power in watts (P) is equal to the product of the voltage (E) and the current (I). The total power used at 6 amps and 120 volts is equal to 720 watts. If the voltage was 240 volts, the total power would be 240 volts times 6 amps, or 1440 watts.
To calculate amperage, use the formula: Amperage = Wattage / Voltage. For a household appliance with a wattage of 720 and a standard voltage of 120 volts, the amperage would be 6 amps. (720 watts / 120 volts = 6 amps).
