How to create your own resistor

How to create your own resistor

Check out this simple tip that Michael sent me:

MICHAEL: “I was making a small practice audio amplifier, and was in need of a 2.5 Ohm resistor. I didn’t
have one, and didn’t want to wait for an order to be fulfilled.

If resistors are made of carbon, and variable resistors have a carbon raceway; then perhaps, I could make one. I wrapped each end of a segment of pencil lead with wire, soldered the wires in place, adjusting the distance between the wires until I got the value I needed. How’s that for a quick fix?”

OYVIND: Great tip. Easy and simple. And it makes the resistor less of a mystery. Thanks for sharing!

Keep on Soldering!
