You need a strong magnet, a big coil of enameled copper wire, a large capacitor, and an efficient LED. And a few odds and ends. The basic design uses the magnet and coil as a generator, or dynamo. As you shake the assembly, the magnet slides up and down past the coil, generating voltage. You rectify the AC voltage and use it to charge the capacitor. You then discharge the cap through the LED to make light.
What else can I help you with?
If you have a garden light that charges 3 1.2V batteries what Voltage would the light bulb be?
It's probably only a 1.2V LED. It just depends if the batteries are connected in series or parallel.
If 2 batteries in a simple circuit are arranged neg to neg terminals touching will the bulb light?
If you put two batteries of the same voltage with like terminals touching each other in series the equal, but opposite voltages will cancel each other and the light bulb will not light, because there is no current flowing through it.
When a three light circuit is connected in series with 2 6V batteries what is the voltage across each of the lights?
If a three light circuit is connected in series with two 6V batteries, and the three lights are identical, the voltage across each of the lights is 12V divided by 3, or 4V.
What produces more light series or parallel circuits?
A series circuit will produce more voltage. For example, two 12 volt automotive batteries both have a 600 amp capacity. Connect the 2 batteries in series and you will have 24 volts with 600 amp capacity. Connect the 2 batteries in parallel and you will have 12 volts with 1200 amp capacity.
How do you design electric circuit for flashing light?
The easiest way is to use an LM555 chip specs and design hints are all over the Internet Use as a as-table oscillator configuration
Can a Nerf lumitron shoot without batteries?
Yes, the Nerf Vortex Lumitron can fire without batteries. The batteries are only used with the magazine to light up the discs as they are fired, so batteries aren't a necessary thing to fire the blaster.
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 do shake flashlights work and generate power without the need for batteries or electricity?
Shake flashlights work by converting mechanical energy from shaking into electrical energy. Inside the flashlight, there is a magnet that moves back and forth when the flashlight is shaken. This movement induces a current in a coil of wire, which generates electricity to power the light. This process eliminates the need for batteries or electricity to operate the flashlight.
How many batteries does it take to light a big light bulb?
You dont need batteries to light a lightbulb!
Does the Nerf N-strike firefly rev-8 works without batteries?
No, you can still shoot it. The only thing you need batteries for is to make the revolving barrel light up.
What type of batteries are used by the Cordless Picture Light?
4 AA batteries is what the light takes.
What is the difference between a batteries in a flashlight and batteries in a car?
batteries in a car is bigger and cause exploions and flash light dont they bring light to the flashligt
How many batteries can light up bulbs?
This question cannot be answered without knowing at least the voltage of the light bulbs and also the voltage of the battery that is being asked about.
My 98 camaro is shaking you replaced the plusand wires but the problem contines and the check engine light is on what could be the problem?
bat motor mounts cause the shaking a knock sensor realizing its shaking is the light get new mounts
Can a car battery light a bulb?
Most car batteries are 12 volts. They can light 12 volt bulbs. The bulbs in your house are likely 120 volt bulbs. A car battery will not light those without some very special equipment, or unless you were to wire ten car batteries in series.
Light am led light out of batteries?
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.
How can I illuminate my bike wheels without using any batteries?
You can illuminate your bike wheels without using batteries by using reflective tape or stickers that reflect light from streetlights or car headlights. Another option is to use wheel lights that are powered by motion or friction as you ride.
