The 200 watts on an amplifer would refer to output if it were turned up all the way. This does not tell you how much electricity the amplifier would use. There is some power lost from heat, but we don't know just how much, from the information above.

How many amps does a 65 watt light bulb use?
Amps x volts = watts So, assuming you are running on 110 volt line, the answer is 65 watts/110 volts=.591 amps.
How many amps in a 300watt bulb?
There are zero amps in a 300 watt bulb. Watts are the product of amps times volts. W = A x V. To find amperage use the equation A = W/V. If you find the voltage of the 300 watt bulb uses, divide the wattage by the voltage and it will give you the amps of a 300 watt bulb.
What equation would you use to calculate how much current in AMPs is required to achieve the full 100 to output from a volt bulb?
The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.
How many amps does a 120v 50w halogen light bulb use?
At what voltage? Until you tell me the voltage I can't give you an answer. To find out Amps you need to divide the Watts by the Volts. At 120V you have 0.4 amps. At 12V you have 4 amps.
How much wattage will the ballast and a 150 watt hps bulb use?
About 1.66 amps at 120 volts Ballasts have stickers on them that tell you the exact amps per the voltage that you are running
How many amperes does a standard 60 watt light bulb use?
Watts = Volts X Amps. Amps=Watt / Volts. So, with a 240V mains, a 60W bulb draws 0.25amps. On a 12 system (car/auto) a 60W bulb draws 5 amps. On a 110V mains, a 60W bulb draws .55 Amps.
How many amps does a 50 watt bulb use?
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.
How many watts does a 12volt X 65milliamp bulb use?
Watts = Amps x Volts. Milliamps to amps move the decimal place three places to the left.
How many amps does a 65 watt light bulb use?
Amps x volts = watts So, assuming you are running on 110 volt line, the answer is 65 watts/110 volts=.591 amps.
How many amp hours does a 23 watt bulb use?
The formula for finding amperage is I = W/E. Amps = Watts/Volts. Without the value of the voltage to the bulb this question can not be answered.
How many amps in a 300watt bulb?
There are zero amps in a 300 watt bulb. Watts are the product of amps times volts. W = A x V. To find amperage use the equation A = W/V. If you find the voltage of the 300 watt bulb uses, divide the wattage by the voltage and it will give you the amps of a 300 watt bulb.

How many amps does ATM use?
10 amps

How many amp hours does a 13 watt bulb use?
A 13W bulb consumes 13W/110V=0.118 A.If you use it for an hour, it consumes 0.118 Ah, for 2 hours 0.236 Ah, and so on..AnswerLamps don't use ampere hours, as this is simply a unit of measurement for electric charge. You probably mean 'watt hours' which is a measure of energy. A 13-W lamp will use 13 Wh for each hour it is used.
How many amps does a toaster use?
a regular toaster uses about 12.5 amps
