Hi,
How is it possible that a close circuit have capacitance? i printed a conductive filament with a shape of 8/9 rhombus connected in a raw and if i connect my multimeter to the end of the structure it gives me capacitance. What can be an explanation for that?
P.S. Sorry about my english

 

Welcome to AAC!

Every conductor has capacitance.
What is the value of the capacitance that you measured with the meter?

 

Thank you for your reply, It is 13 pF.

 

So the shape more or less is this one ---------<><><><><><><>. Why if i stretch this shape it changes the value?
Thank you

 

What is the new capacitance value?
Yes, it depends on the shape.
Any capacitance value from 0 to 20pF is not strange.

 

Yes it's stays in that range. So it possible that the capacitance change because the sides of the rhombus get closer?

Another question. Imagine two of these conductive structures, one on the top of the other separated by a non conductive material. Can I create a parallel plate capacitor in that way?

Thank you

 

And stretching the all structure the capacitance should change increasing right?

 

Yes, you can create a parallel plate capacitor in that manner.

The capacitance will depend on the shape, area, spacing, and insulating material used.
