Electric Conductivity

Basic CMYK

This is my second comic for today, and I’m feeling rather tired, so don’t be surprised if you find lots of spelling and grammar mistakes.

Yeah, so basically electric conductivity has the same principle as heat conductivity. (If you haven’t seen it, it’s just 2 posts below this one. Every material is known as a conductor. An electrical conductor is something that can transfer electricity to another thing. However, some things are better at others at conducting electricity. Those which are good are known as good conductors and those which are bad conductors are known as insulators. The best conductor is silver and the best insulator is polytetrafluoroethylene which is a synthetic fluoropolymer of tetrafluoroethylene (that was from Wikipedia) It is more commonly known as Teflon, and it is used to coat frying pans.

By the way, you might be surprised to learn that water is not a very good conductor of electricity. This might be a bit of a shock for you to learn, as there are always those signs that tell you not to swim in the pool during a storm. Mind you, that dosen’t mean you can swim in the pool when there’s lightning flashing. It is very probable that you will have to attend a funeral very soon encased in a coffin. This is because although water itself is not a very good conductor, with just the slightest bit of salt and it’s conductivity power will expand tremendously.

To test whether something is a good or an insulator, you will need a battery, two wires, a lightbulb and your material (it must be something like a sheet). You connect one end of the wire to one end of the battery. You then clip your lightbulb onto the wire. You then put clip your material to the other end of that wire. After that, you clip on the material on one end of the OTHER wire. Then you connect the remaining end with the battery. It should look something like this:

Electric conductivity

If the lightbulb lights up, then the material is a good conductor

If the lightbulb does not light up, the the material is an insulator

If the lightbulb half lights up, then you’re probably dreaming, so start pinching your arm.

Oh by the way, don’t worry about Kiat, he survived the lighting bolt. There’s this guy called Roy Sullivan who survived 7 lightning strikes. And no, he did not die from an 8th lightning strike, it was from a gunshot he shot at himself over an requited love. (long story) Unfortunately for the author, Kiat does not seem to enjoy our perfectly harmless experiment. The author is now in hiding.
