Can a 6 volt battery light up a 40 watt bulb?
No, a 6 volt battery is not strong enough to power a 40 watt bulb, which typically requires around 12 volts to operate efficiently. You would need a higher voltage power source to light up a 40 watt bulb.
A 75 watts110 volts bulb is connected in parallel with a 40 watts110 volts bulb. What is its net resistance?
We have two bulb in parallel debiting 75 + 40 = 115 watts under 110 volts. I -current amperes V -potential volts W -power watts R -resistance ohms knowing W = V*I V = I*R W = R*I2 Then: 115 watts = 110 volts * I => I = 115/110 = 1,045 amperes R = 115/(115/110)2 = 1102 / 115 = 105,217 ohms ------------------------------------------------------------------------------------------- Another way: First get the resistance of each bulb. Then we know that Rparallel = 1/(1/R1 + 1/R2 ) 75 watts = 110 volts * I => I = 75/110 ampere. R1 = 75/(75/110)2 = 1102/ 75 = 161,333 ohms. for the other bulb 40watts = 110 volts * I => I = 40/110 ampere. R2 = 40/(40/110)2 = 1102/ 40 = 302,5 ohms. meaning Rparallel = 1/(1/161,333+1/302,5) = 105,217 ohms That it's
How many ohms is 5 watt light bulb?
To calculate the resistance of a 5 watt light bulb, you can use the formula P = V^2 / R, where P is power (5 watts) and V is voltage (typically around 120V for a household light bulb). Rearranging the formula to solve for resistance, you get R = V^2 / P. Plugging in the values, R = (120V)^2 / 5W = 2880 ohms. So, a 5 watt light bulb at 120V would have a resistance of 2880 ohms.
What it is the difference between 100 watts and 75 watt light bulb?
The main difference between a 100-watt and a 75-watt light bulb is the amount of light output they produce. A 100-watt bulb will be brighter and consume more energy compared to a 75-watt bulb. The 100-watt bulb may also generate more heat than the 75-watt bulb.
What is the resistance of a 28 watt bulb?
That depends on what voltage it's designed to operate from. Power = (voltage)2 / R R = Voltage2 / power If it's a 117-volt bulb, R = (117)2 / 28 = 489 ohms. If it's a 240-volt bulb, R = (240)2 / 28 = 2,057 ohms.
What is the recommended wattage for a replacement bulb for a 40 watt fridge bulb?
The recommended wattage for a replacement bulb for a 40 watt fridge bulb is also 40 watts.
What does 40 watts bulb mean?
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
How many watts are in a security light with a 40 watt bulb?
If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
What is the incandescent equivalent of a 40 Watt halogen bulb?
A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.
What is the brightness level of a 5 watt LED bulb equivalent?
The brightness level of a 5 watt LED bulb is equivalent to a 40 watt incandescent bulb.
Which will last longer a 40 watt bulb or a 60 watt bulb?
They will last about the same period of time.
How do you use the word dimmer in a sentence?
A 40 watt bulb is dimmer than a 100 watt bulb.
For bulbs connected in series the high watt bulb has high resistance?
No, the highest wattage bulb will have the lowest resistance.
A 60-watt 120 volt lamp requires morecurrrent than a 40 watt 120 volt lamp?
Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.
What is the best brand to buy for a 40 watt equivalent LED bulb?
The best brand to buy for a 40 watt equivalent LED bulb is Philips.
What is a G light bulb?
looking for a 40 watt g bulb what is that?
What is the minimum watt of a light bulb for night reading?
