The 12 v light should have the voltage and the power in watts printed on it. When it is running, it uses that amount of watts continuously. The energy is measured by the watt-hours, in other words the watts multiplied by the number of hours it runs for. 1000 watt hours makes 1 kilowatt-hour, which is a Unit on the electricity bill.

How many watts is light bulb 120 VAC 60Hz 300mA?
Multiply the current by the voltage: 120 times 0.3, which is 40 watts.
How many watts in 7200mha?
To convert mAh (milliamp hours) to watts, you need to know the voltage as well. If we assume a standard voltage of 3.7V for a typical lithium-ion battery, then 7200mAh would be equivalent to 26.64 watt-hours (7200mAh x 3.7V / 1000).
0.36 amps equals watts?
Have to know the voltage to answer this question.
Find amp's when watts and voltage is known?
The formula you are looking for is I = W/E.
How voltage is 350kv to watts?
To convert voltage to watts, you also need to know the current in the circuit. The formula to calculate power (watts) is: power = voltage x current. As voltage alone is given, you would also need the current flowing through the circuit to accurately determine the power in watts. Without the current value, it is not possible to convert voltage directly to watts.
What cable to use for light of 540 watts?
Need a voltage to answer this question.
Formula to figure out watts when you have voltage and mAh?
Voltage times current is equivalent to power (watts). You need to keep in mind that milli amp hours (mAh) is amps with a unit of time - it's a specific amount of current for 1 hour. Watts is an instananeous measurement; watt hours is the equivalent you should be looking for. there is no direct conversion for watts from voltage and mAh.
How long W light on ah battery?
The problem here is that "Ah" (ampere-hours) is not a unit of energy. To convert that to units of energy, you need to multiply by the voltage of the battery. The result, of course, will vary depending on the battery type.The result of this multiplication would give you ampere-hours-volts, or watts-hours (watts times hours). Therefore, you can then divide by the number of watts used, to obtain the time (in hours).
How many watts does a 18 watt floresent light bulb consume?
Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
How many amps in a low voltage light bulb?
Look on the light bulb for the voltage and the power in watts. Then divide the watts by the voltage and that gives the amps. Some CFL bulbs also state the current as well as the voltage and power, which is because they can have a poor power factor.
Does amps times voltage equal watthours?
Amps times volts = watts Watts measures the rate of power usage. watts times hours = watt hours Watt hours is a measure of the amount of power used.
How many watts is light bulb 120 VAC 60Hz 300mA?
Multiply the current by the voltage: 120 times 0.3, which is 40 watts.
If i use 7000 watts per day how many amp hours per day would this be?
To obtain amps from watts a voltage must be given.
How many watts in 7200mha?
To convert mAh (milliamp hours) to watts, you need to know the voltage as well. If we assume a standard voltage of 3.7V for a typical lithium-ion battery, then 7200mAh would be equivalent to 26.64 watt-hours (7200mAh x 3.7V / 1000).
How much does it cost to run a light bulb?
It depends on the bulb, how many watts it is. All bulbs are marked with the correct voltage and the power taken, in watts. You multiply the watts by the number of hours to find the watt-hours of energy used. Then divide by 1000 to find the kilowatt-hours. A kilowatt-hour is also called a unit and you pay about £0.15 for a unit of electricity. Let's say it's a 100 watt bulb running for 24 hours. That uses 2400 watt-hours or 2.4 kilowatt-hours, which costs about 2.4 x £0.15 which is £0.36.
