Create a Capacitor
Intro: Create a Capacitor
today i am going to show you how to make a capacitor.it is super simple and works great!not like real capacitors but it works well for a handmade one.it is great science projects and classes and anyone can build it. it is the new version of the leyden jar.this handmade capacitor can store good amount of energy.but less than real one.once you built it you can experiment with its science and size.
visit my profile:https://www.instructables.com/member/argha+halder/ to see some of my more such projects.if you have any question feel free to ask.i will try to ask them according to my ability.
STEP 1: Things You Will Need
1)an empty plastic or glass container with cap.
2)alluminium foil
3)paper clip
4)glue
5)water
6)salt
STEP 2: Making the Capacitor
STEP 3:
STEP 4:
make sure the alluminium foil does not touch the water.
STEP 5:
STEP 6:
STEP 7: Charging It!
now with a voltmetre test it!you will see it works
STEP 8: How Does It Work
STEP 9: What Makes It Stronger
STEP 10: Troubleshooting
make sure that the alluminium and paper clip does not touch each other.that thing you are using to charge it is in good condition.
i dont know english much as it is not my mother tongue language.and so if any mistake help me find it.give some more ideas.feel free to ask questions.i will try to answer them as much as possible for me.bye!have a nice day

I want to do a project proposal.... And my target was to construct a capacitor
I need your help cause I appreciate for ur effort

I want to made a capacitor of which the capacitance could change with different loading on it. and draw a calibration curve that reveal the relationship between capacitance and load. could u give me some suggestions?

That's a good idea. You can do that, but what happens is its capacitance depends not only on the foils and insulators, but also on your perfection. If you can make the foils really even and glue it nicely it can give you better results than one thats not done neatly. So you have to build different capacitors and check out the capacitance. And the relationship after checking the capacitance is really difficult to draw, because there are more than one or two factors to consider, like the foil size, evenness of the foils, thickness of the insulator, the electrolyte used inside. So it might reveal an exponential relationship, because not always the results will come linear.So you got to give it a try and find out! And sorry for being so hazy and unclear in my instructions. Have fun building and experimenting!!

Yeah~ it is just a idea coming out of my minds. there are truly too many factors to control. I just guess that for those equipment that used to weigh trucks, they may be actually a kind a capacitor of which the capacity varies with different loads on it. and the may have a reasonable fitting line that reveals the relationship very well..

Yeah pretty much, actually if you want to make a capacitor that you can count the capacitance get two pieces of aluminium foil and put a paper in the middle.This you can calculate the capacitance using the theory of capacitance, look at this video made by rimstar for better idea : https://www.youtube.com/watch?v=GveI9gXIsHw

I have a 4th grade student who's trying to power a small light bulb using a
homemade leyden jar for his science fair project. Is this possible with a pint-sized jar? Any tips?
AH Electronics 10 years ago
yes it is, but note that it will not stay lighted for more than 10 seconds I think, as did mine. So I suggest to use a jar almost the size of a jam jar. It would would be better in that way and also easier. Also use a good highly charged battery if possible, because if the leyden jar is not charged well then it might not light for long time. and good luck to your student for the science fair

Thanks for the tips, argha halder! Science fair is going well!
