i want to buy some wire to use as jumper wire to bridge two components on a circuit board.
but what thickness do i need .i have read that tinned copper 24 gauge is correct . is this right ,
and can you give me anymore info.
thank you.

If fairly low current, there is 6 core single strand insulated telephone wire. Home Depot etc.
CAT5 solid strand.
For negligible current, I use wire wrap conductor.

I buy 100 alagator clips off ebay and cut vering lengths of wire and solder up my own. The jumpers on ebay are not worth the effort.
I use 14 AWG and that works for 99.9 of the stuff I do. Nice to have a pile of jumpers and good ones at that.

Most jumpers on ebay (male-female) are intended for bread board.

I just use 28AWG enamelled copper wire that has solder through insulation. A small reel lasts a long time. It's fine for connecting components together on a breadboard anything else may require a thicker wire for larger currents.

Odds are that you have something old, now unused that you can get the wire from, whether it is solid core bell wire or ethernet cable, multi-strand extension cord or appliance wire, enamelled copper windings off an old transformer, etc.

I mean if you so seldom use wire that you have to buy some for a single jumper, I would see what I could cannibalize, but of course you must consider the minimums of current and acceptable losses as already mentioned, but it won't hurt (if you have space and a mechanical means of fixing it in place) to use a bit small gauge (larger diameter) wire than necessary. This is very commonly done when the design isn't budget constrained down to the last pennies or in your case, saves many pennies if you already have some wire that would work.

I bought the 1/2 Kg reel I mentioned some 15 years ago and it still has plenty on it. Wasn't horribly expensive either
