In summary, The conversation revolves around building a crank generator from a pipe and copper wire. The person is wondering how much copper wire is needed to produce a 3v output and the other person suggests calculating the circumference of the pipe and multiplying it by 400. They also discuss the factors that can affect the amount of power generated and recommend building a prototype to measure the results. The link provided shows a prototype lighting up an LED and mentions using 500 turns of wire instead of 400. They also mention that power is measured in watts, not volts. The conversation ends with a good luck wish for the experiment.

Calculate the circumference of the pipe you are winding it around, then multiply that by 400.

Any idea how much it can produce?

depends on many factors including, but not limited to ...
strength of magnet, speed of rotation of magnet or coil ... depending on your construction
you are going to have to build a prototype and experiment with measuring the results of different setups

The link you provided is post #1 showed it lighting a LED. That is a first guess of how much it can make.

By the way, we measure power in watts, not volts.

By the way, the link said 500 turns, not 400,

Good luck, it sounds like a fun experiment.

Thanks again for the advice
 

Related to Crank Generator: How Much Copper Wound Needed for 3V Output?

1. How does a crank generator work?

A crank generator works by converting mechanical energy from the turning of a crank into electrical energy through the use of magnets and coils of copper wire.

2. What is the purpose of a crank generator?

The purpose of a crank generator is to provide a portable and renewable source of electricity for small devices or emergency situations.

3. How much copper wire is needed for a 3V output from a crank generator?

The amount of copper wire needed for a 3V output from a crank generator will vary depending on the design and efficiency of the generator. Generally, the more copper wire wound around the generator, the higher the output voltage will be.

4. Can a crank generator be used to power larger devices?

No, a crank generator is not powerful enough to provide electricity for larger devices. It is best suited for small devices such as radios, flashlights, or cell phones.

5. Are there any safety precautions to keep in mind when using a crank generator?

Yes, it is important to not over-crank the generator as it can cause damage to the internal components. Also, be cautious of any sharp edges on the crank and handle it carefully to avoid injury.
