How much current is consumed for a tube light?
If u r living in countries supplying 110V then the current flowing through ur 40W tube light is 0.367amps. But, if u r living in countries supplying 220V then the current flowing will be reduced by half being only 0.1835amps. Zero. When it is turned off ,there are no Amperes consumed.
How many watts can 1 Amp hold?
120 watts
At 120V, 120 watts make 1 amp. That means that 1 amp = 120 watts.
What is the power of tube light?
A fluorescent tube or bulb can produce 50-100 lumens per watt. Compact fluorescent lights (CFL): These use gas, mercury particles and phosphor to create light. Most CFLs have a charge-up time, and also need more watts to light up.
How do I calculate amps from watts?
Converting watts to amps can be done using the power formula, which states that I = P ÷ E, where P is power measured in watts, I is current measured in amps, and E is voltage measured in volts. Thus, the current I in amps is equal to the power P in watts divided by the voltage V in volts.
How many amps does a 40 watt fluorescent bulb use?
0.36 Amps
A 40 Watts bulb is capable of drawing 0.36 Amps to operate.
How many watts does a 40 watt bulb use in an hour?
40 watt light bulb would use 40 watt per hour.
How many watts can a 40 amp breaker handle?
9,600 watts
40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts.
How much power does a 40W bulb use?

How do you calculate power consumption of a light bulb?
To find the kilowatt-hours your light bulb consumes per month, multiply the kilowatt use by the number of hours it’s on each month. Example 1: The incandescent bulb uses 0.06 kW of power and is on for 180 hours a month. Its energy usage is (0.06 kW * 180 hours/month) = 10.8 kilowatt-hours per month.
