How long will a 1.5 volt Duracell AA power 1.5 volt light bulb?
The duration a 1.5-volt Duracell AA battery can power a 1.5-volt light bulb depends on the battery's capacity (measured in milliamp-hours) and the power consumption of the bulb (measured in watts). Typically, a standard AA battery has a capacity of around 2000-3000 mAh, while a 1.5-volt bulb may consume around 0.5 watts. This could result in the battery powering the bulb for several hours, but the exact time will vary based on the specific battery and bulb used.
What uses more energy a 60 watt light bulb or 18 watt light bulb?
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

Does wavelength determine the watts of a bulb?
The Wattage of a bulb tell you how much power (energy per second) you put into it. The energy will come out mostly as heat but obviously also light. The wavelength has the units of length and tells you what type and color of light it generates. The energy in each particle (photon) of light is dependent on the wavelength but the total power input isn't directly related. You can have both high and low input power infra red (long wavelength) and Ultraviolet (short wavelength) lamps.
If a lamp bulb is rated at 100 watt why is a time factor not in the rating?
The wattage rating of a lamp bulb is a measure of the power it consumes, not the duration it operates for. The rating tells you how much power the bulb will use when it is in operation, but it does not provide information about how long the bulb will last before needing to be replaced.
How can a 60 watt bulb use the same power as a 60 watt bulb can in a second?
A 60 watt bulb uses 60 watts of power continuously per second. It is consistent with the definition of power, which is the rate at which energy is consumed or produced. Therefore, a 60 watt bulb would use the same amount of power as another 60 watt bulb within the same timeframe of a second.
How does a simple circuit with a battery and a light bulb work?
In a simple circuit with a battery and a light bulb, the battery provides electrical energy that flows through the wires to the light bulb. The electrical energy causes the filament in the light bulb to heat up and emit light. This process continues as long as the circuit remains closed and the battery has power.
What happens to a bulb when you move it to the battery on a circuit?
It doesn't matter where the bulb is in respect to the battery, as long as the circuit is complete, the bulb will light up.
Do you need a battery to light a light bulb in a circuit?
Yes as long as the battery and bulb are rated at the same voltage. (Boy Scouts do it every day with flashlights.)
How long will a AA battery last in keeping a light bulb lit?
i year
How long will a fruit power a light bulb?
The duration that a fruit can power a light bulb will vary depending on the type of fruit and the size of the bulb. Generally, fruits can power a simple LED light for a few hours to a few days.
Can i light a light bulb with a battery and a paper clip?
It is possible to light a small LED light bulb using a battery and a paper clip, as long as the paper clip is used to create a closed circuit between the battery's terminals and the light bulb. However, be cautious as this setup can potentially overheat and cause a fire hazard. It is always safer to use proper tools and equipment designed for this purpose.
How can I change a long light bulb?
To change a long light bulb, first turn off the power to the fixture. Use a ladder to reach the bulb, then carefully unscrew the old bulb and replace it with a new one. Be sure to securely tighten the new bulb and turn the power back on to test it.
Where could you find a simple electrical circuit?
In a flashlight. You have a power supply (the battery), a load (the bulb), and a switch to prevent current in the loop when you don't need light. It couldn't be any simpler, unless you eliminate the switch and let the light shine for as long as the battery survives.
Why does a torch light go dimmer if you leave it on for long?
A torch light goes dimmer over time because the battery drains as it provides power to the bulb. As the battery's charge decreases, it can no longer supply sufficient voltage, leading to reduced brightness. Additionally, the bulb itself may heat up and experience changes in its filament or LED components, which can further diminish light output.
How does a flashlight work?
A flashlight has a power source (usually ordinary batteries), a light source of some sort (a light bulb or LED, for example), and some electrical wiring to connect them, with a switch to turn it on and off. The power source makes the light source give off light.
How much energy do you save with 10 light bulbs off?
That depends on the power used by each light bulb. Look at the specifications for a specific light bulb, then multiply the power by 10. Note that energy = power x time; that is to say, the energy spent by a light bulb depends on its power, but also on how long you keep it on. Specifically, watts = joules x seconds.
