Can you use jumper wires to test parallel circuits?

I'm trying to find the proper valued cap to go across a 20k 1/4w resistor. I'm using jumpers that are approx. 1 foot long. How about it guys? Will it work?

It will be noisy, but it should work. I test components will alligator clip wires all the time. Just don't kill yourself doing it (I.e., use the appropriate amount of fear & respect)!

Yes-Amen to that! Ok-so let me ask you this: let's say with the aforementioned resistor, I had a 500pf cap, and another 1000pf cap. Could I double those two individual caps together within the same clips and see what it would would like with a 1500pf cap? Is that how that would work?

Use the one for parallel capacitors.

Big difference between testing across a plate vs cathode vs other resistors using this approach.

In what way? I'm attempting to do this with a voltage divider, wherein I'm paralleling R2. R1 is preceded by the 12ax7 plate, but there is a cap in between it and the plate.

So how would this pan out?
