It will depend on what battery you need. I use rechargeable AAA and AA batteries for my lights. Bike computer batteries will vary depending on the type used.
If it is working and produces light, then it is a source of light.
It's probably only a 1.2V LED. It just depends if the batteries are connected in series or parallel.
they have citric acid in them and it replaces sulphuric acid in batteries. :-)
Connect an LED, two AA batteries, and a resistor of around 100-150 ohms, all in series.If the LED doesn't light, then turn either the LED or the batteries around in the circuit.
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).
You dont need batteries to light a lightbulb!
4 AA batteries is what the light takes.
That would be an LED or Light Emitting Diode an LED is a light
Light Emitting Diode - LED
batteries in a car is bigger and cause exploions and flash light dont they bring light to the flashligt
LED stands for Light-Emitting Diode.
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.
