12 volt batteries vary in size. You need to look at the amp hours of a battery and multiply by the voltage. So, a 100 amp hour battery at 12 volts is 1200 watt hours. 30 watt bulb will eat that up at 30 watts and hour. 1200 divided by 30 is 40 hours. Simple huh!?
*Something to keep in mind is if your 30 Watt light bulb is rated 30 watts at 12 volts. If it is rated 30 watts at 24 volts, 110 volts or another voltage it will also change the length of time your battery will last.
What else can I help you with?
How many D batteries would it take to power a 52 volt light bulb?
Assuming a standard D battery has a voltage of 1.5 volts, it would take approximately 35 D batteries (52 volts / 1.5 volts per battery = 34.67). However, in reality, you cannot directly power a 52 volt light bulb using D batteries as the voltages do not match.
How many Mexicans does it take to unscrew a light bulb?
One Mexican can unscrew a light bulb just like anyone else. The number of people needed would depend on the complexity of the task, not their nationality.
How many kwh does a 200w light bulb use?
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
How many volts do you need to light up a 15 watts light bulb?
15.
Which burns out faster a small light bulb or a large light bulb?
The size of the bulb isn't related to the time in which it will burn out, it's related to it's quality and how many times you turn it on and off.
Could batteries light a light bulb?
Yes, even a potato can light a light bulb. Yes. If the batteries match the voltage of the bulb, they can light it. Flashlights have bulbs and batteries that power them. If you mean a household light bulb, then you'd need many batteries in series (80 of the 1.5 volt batteries).
How many batteries does it take to light a big light bulb?
You dont need batteries to light a lightbulb!
How many batteries does it take to light up a 25 watt bulb?
Is the bulb a 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?This question cannot be answered without knowing at least the voltage of the light bulb and also the voltages of the batteries that are being asked about.
How many D batteries would it take to power a 52 volt light bulb?
Assuming a standard D battery has a voltage of 1.5 volts, it would take approximately 35 D batteries (52 volts / 1.5 volts per battery = 34.67). However, in reality, you cannot directly power a 52 volt light bulb using D batteries as the voltages do not match.
What might happen to a bulb if you added too many extra batteries to the circuit?
If you added more batteries in parallel, then the bulb would shine for a long time. If you added more batteries in series, then the bulb would burn very brightly for a short time and then 'burn out'.
How many batteries does it take to burnout a light bulb?
The number of batteries needed to burn out a light bulb depends on the type of battery and the power rating of the light bulb. Typically, for a standard household light bulb (60-100 watts), one high-power battery or two to three regular batteries might be enough to burn it out due to overload. However, attempting to intentionally burn out a light bulb can be dangerous and is not recommended.
Does the number of batteries affects bulb brightness?
Yes, the number of batteries affects a bulb's brightness. More batteries in a circuit can increase the voltage supplied to the bulb, resulting in a brighter light output. However, using too many batteries can also risk damaging the bulb if the voltage exceeds its rated capacity. Therefore, there's an optimal number of batteries that can enhance brightness without causing damage.
What happens when a bulb is attached to a battery?
When a bulb is attached to a battery or a cell as scientists call it, the bulb glows. If you want a bulb to glow more and more brighter, it depends on how many batteries you attached to the bulb. If you attach a lot of batteries at the same time, the bulb might even explode or burn out. The wires that hold the interaction between a light bulb and the battery is electricity. The electricity flows through the wires and touches the bulb and that is how a light bulb glows.
What might happen to the bulb if you added too many extra batteries to the circuit?
If you added the batteries in parallel, then the bulb would stay on for a long time and nobody would get any sleep. If you added the batteries in series, then the voltage across the bulb would eventually become excessive and the bulb would burn out.
How many 1.5 volt batteries does take to light up a big light bulb?
Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.
How many lemons does it take to make a light bulb light?
it takes 3,003,494,560,327,650,836,140,520,347,257,345,803,465,876,324,065,086,237,248 and it still might not get done
How many switch must the bulb need if there are 2 batteries?
A bulb must have a minimum of 1 switch if there are 2 batteries. The batteries can be connected in together via wires to prevent the need for a second switch.
