How many watts can an led need to light up?
It depends on the color of the led you have. Normally it changes between 1.5 V and 2.5 V. But if you need to use white or purple leds those leds need more power like 4-5Volts. Im gonna calculate for a standart red led, a red led needs 20 mA and 2 volts to light up. So we know the formula that we can calculate how many watts does the led need, P = U * I P = 2 * 0.02 = 0.04 W. I used the average values. I hope I didnt make any mistake :)
How can I convert lux to watts in order to determine the power of light emitted by a source?
To convert lux to watts, you need to know the luminous efficacy of the light source in lumens per watt. Then, you can use the formula: Power (watts) Illuminance (lux) x Area (square meters) x Luminous Efficacy (lumens per watt). This calculation will help you determine the power of light emitted by a source.
How many watts in 7000 joules?
To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
What temperature is 1100 watts into Celsius?
To convert watts to temperature, you need more information such as the specific heat capacity of the material being heated. Watts is a measure of power, not temperature.
How many watts are in 13 amps?
Excellent question. That depends on the voltage, for 120 VAC, the answer is 156 watts. PIE, Power (in watts) = current (amps) X Voltage . For 12 VDC, 15.6 watts. An interesting asside, if you ohms check a 120 watt (should draw 1 amp) incandesent light bulb, it will read much less than you would expect (120 ohms). Turns out, the filament at room temp is much more conductive.
How many watts does it take to power a 24 voltage strobe light?
To calculate the power in watts, you would need to know the current the strobe light draws at 24 volts from its specifications. You can then use the formula P (Watts) = V (Voltage) x I (Current) to determine the power consumption. Without the current rating, it's not possible to provide an exact wattage.
How many volts do you need to light up a 15 watts light bulb?
15.
How many watts does a tube light need?
Depends on the specific light. A range might be between 10 and 40 watts per tube for most applications in a residence or small business.
What cable to use for light of 540 watts?
Need a voltage to answer this question.
How many watts need for seven ampere's and 120 volt's?
770 watts.
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many watts does a nintendo64 need?
26watts
How many watts does a small car need?
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
How many watts in 120v 60Hz?
You need amps
How many watts need on dialysis machine?
350
How many watts does a 12 volt low voltage landscape light use in 4 hours?
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 per second does a hair straightener need?
hair straightener uses 1500 watts
