Hi. The resistor is not shown in the picture but it is connected in series to the capacitor. And by open, I meant the plates are not covered by anything such as a case or any shield. Yes, I'm supplying it with a constant 5V DC source and I believe the amount of water between the plates affects...

I'm not concerned about its capacitance and I forgot to mention I'm using a constant DC source. Also, I insulated my plates with an insulating varnish.

Oh I see. Well, I can't just give up on this experiment because it's the foundation of my thesis. But nonetheless, I appreciate your the input. :)

As I mentioned, the capacitor is fixed in the water container so I can't shake it. And I don't know what help can shaking the capacitor can do. haha.

Hi everyone. I have a problem with my device. It consists of a parallel plate capacitor with plates made of galvanized iron. Each plate's area is 1mx1inch. It's connected to a bleeder resistor and basically, the circuit is just a simple RC circuit. The source I'm using is a constant 5V DC...

I understand. And I'm really sorry for not providing any images of the setup. Also, I am very grateful for your responses. :) When I get the chance to take a pic of the setup, i will post it here. Probably next week when classes are back from the lent holidays.

I realized that. That's why I used an insulating varnish on the plates.

When I tried it without water, the voltage across the capacitor is 5V and constant. With water, if I disconnect it from the source, the decrease in voltage just goes faster. With constant 5V source, the decrease in voltage happens but slower. Do you think the small capacitance is a factor why...

I don't have a pic of the setup with me. But I promise I know if it's connected in series or parallel. And i measure the voltage across the capacitor in parallel. And just to add, I'm using water as the dielectric material between the plates. So there's a portion of the capacitor that has water...

I swear I'm reading the voltage in parallel. :(

In parallel.

And hey, by the way, thanks for replying. :)

Actually, that's what puzzles me. The 5V DC source is constant and i don't unplug it. But still, the voltage still drops.

Oh. I forgot about the details. Sorry about that. I used an insulating varnish on the plates. I'm using a constant 5V DC source. I used a digital multimeter to measure the voltage. And the area is 1m x 1inch so it's like 1x0.0254 m squared.

Hello! I'm hoping someone can help me with my problem. I'm currently working on a low cost parallel plate capacitor. I used a galvanized iron as the plate material since this is a low cost material. The problem is when I measure the voltage across the capacitor, the voltage read peaks at a...
