Question

With your finger on the lead end of a resistor , what affect will it have on the ohm reading?

Answer 1

Good God where did you get a lead ended resister ? , last one I saw was 50 years ago ! To answer your question---one finger on one end only and nothing touching the other end ---no effect at all ! One finger on each end will reduce the value of the resister by connecting your body resistance  ( or one hand ) in parallel , this will vary according to the dryness or dampness etc of your skin or body !!!

Answer 2

Yes, Pete is right grounding one side only would have no effect, but does that actually apply to all lead end resistors Pete?

I was thinking that depended on the resistance of the resistor.

For example if it was a 3000 OHM spark plug the resistance wouldn't be changed right?

:) unless it was firing when your finger touched it, but, if that was the case this question wouldn't be getting asked would it :)
