To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
To calculate the amperage, you can use the formula: Amps = Watts/Volts. For a 65-watt light bulb at 120 volts, the amperage would be 0.54 amps.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
To calculate the amperage, use the formula: Amps = Watts / Volts. In this case, it would be 580 watts / 120 volts = 4.83 amps. Therefore, you would need approximately 4.83 amps for a 580 watt device at 120 volts.
Assuming each 40-watt fluorescent light takes around 0.33 amps, 8 lights would take approximately 2.64 amps in total.
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
A 120 volt table lamp with a 75 watt bulb will pull 0.625 amps. With a 100 watt bulb it will pull 0.833 amps. And with a modern fluorescent 13 watt bulb it will pull 0.108 amps.
A 1450 watt coffee maker will use around 13 amps at 110 volts.
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
you just need one, a general rule of thumb is that the wattage on your amp should be double the wattegae on your sub, hence if you have a 1200 watt sub you'll need a 2400 watt amp
Multiply the volts by the amps to find the watts.
21.4 amps, 2100 wattsManoj
At 120 volts it will pull 4.166 amps. At 240 volts it will pull 2.08 amps.
It is drawing .06 amps.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
To calculate the amperage, you can use the formula: Amps = Watts/Volts. For a 65-watt light bulb at 120 volts, the amperage would be 0.54 amps.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
