How to Power an LED Bulb Using Graphite

In this experiment, let us explore how graphite can be used to power an LED bulb. What you will need… • Pencil (6B, or any pencil with a graphite lead) What you have to do… • Take one of the wires and attach it to the negative terminal on the battery. The other wire should be attached to the positive terminal on the battery (or battery pack). • The other end of the wire attached to the negative terminal of the battery should be attached to the LED bulb. • Use the pencil to draw a rectangle on a piece of paper that is about 3 inches long and 1 inch wide. Shade the shape in completely. • The other end of the wire attached to the positive terminal of the battery should be attached to the graphite drawing. • When you complete all of these connections, the LED bulb should light up. • Try this with different shades of graphite lead. You can use different pencils with varying graphite lead and see what happens. What you just learned… Graphite is an effective electric conductor that you can use to complete a simple circuit. Even the thinnest layer of graphite, known as graphene, can serve just as well. Graphene is the thinnest material there is and is actually a single layer of carbon atom that has a honeycomb pattern. The simplest way to extract graphene begins with graphite - which is actually layers and layers of graphene. To do this, you need a pencil, a sharpener or cutter, tweezers and scotch tape. • Sharpen the pencil and separate the graphite flakes. You can also use a cutter to achieve bigger flakes. • Use the tweezers to place a graphite flake on a piece of scotch tape (about 3 inches long). You can fold the two ends of the tape so you have something to hold on to. • Fold the tape over the graphite and pull it apart again. Do this repeatedly and you will see a honeycomb like graphite on the tape. The thinnest part may even be graphene! This quality of graphene makes it an essential material in the development of nanotechnology. Researchers and manufacturers of computer chips have been testing it to see how its semiconductor qualities can be used to develop thin and flexible electronic components.

Volvo V60 Daytime Running Light - what is the bulb type? Instructions to replace bulb? Or what relay/fuse to replace?

Before you go off to the Stealership to have the bulb replaced, you may want to see if the bulb has lost connectivity at the plug. Since these are LED bulbs, they do not go bad very often or very fast. I believe you should be able to access the plug by removing the main headlight in your car. While this video shows you how to remove the main headlight, it's a little cheesy. You should not have to remove the wire connectors to the headlight to get to the DRL. As far as the DRL, try unplugging/plugging it a few times to see if this rejuvenates the connection. Also, I doubt the problem is a fuse, since normally when you have two bulbs like this (as you do), both bulbs run off the same fuse/relay. Since one is working, you can rule this out

Can a 20w12v halogen bulb work in a socket that originally came with a 10w12v? Do watts matter if volts match?

Aussie gave you a good answer, so if you use the 20w bulb just make sure that the extra heat wo not melt your angel

Growing up back in the 1940,s I seen many home enema bags,and the bulb syringes in homes of friends etc?

Does not matter the color. Mine were red, too, in the 60's

What is electricity in the sense that the same electricity that lights up a bulb can start a computer? Is it used for heat?

Types of energy can be converted into each other.Electricity is very versatile. It can interact in very convenient ways with it's surroundings, more than other energies.Where as heat needs a pressurized system to add directed power and controlled higher energy output, electricity follows conductive strands (metal usually), gravity just does what it wants and blankets crap. So if I have not lost you yet, closer to the actual conversion difference between heat and light if the wave length of the em (electromagnetic) wave that us generated by electricity as it passes through something that is an obstacle, the lack of permeability of said obstacle is usually defined as resistance or impedance.In tern resistance and impedance generates an electromagnetic field. Now changing the current which you can think of as the speed of the electrons, determines the amount of em field potential. The more current the more energy is expended upon the obstacle. This allows something akin to a heat dial.Your body feels heat the most closer to the longer waves of the em spectrum (infrared typically when you feel it and do not see it ya know if you ai not in the blast radius of a nuke). Finally if you change the electron interaction between molecules or orbitals in the material that you are sending this current through, this affects the frequency of the electromagnetic wave meaning you can change the output from something like heat to light (although they are technically the same thing just a different wavelength).What is electricity in the sense that the same electricity that lights up a bulb can start a computer?
