I wonder if anyone could help,
I'm trying to make a 100ohm resistors,
so, I use lead of graphite
but, The object end in failure
so I don't reconcile theory and practice
Somebody might already know the best idea to use.
& Do you have any idea that make a 100ohm resitor?

How are you making your measurements? Terminating the ends of a pencil lead would prove problematic, but could be done. This is for school I would guess.
At this point I bet you are saying, "I should have picked the blue project"...
Sorry, Matrix movie joke.
I've made my own caps before. Sheets of copy paper with aluminum foil. Pouring cooking oil over them increased the capacitance. They were in the ten nanofarad range.
OK there is no need that you have to make a 100 ohm resistor by carbon.
you can also make using nicrome wire.
so you procure a wirewound resistor of 500 ohms 2 watt. carefully remove the outer paint coating and if you get access to removing around30% of the wire from there,
oyou can perhaps wind it on another small ceramic rod . at the ends toy have to grip the nicrome wire cleaned and immediately twist it with say 19 swg bare copper wire and have two or three rounds and tighten.
But beware, this nicrome wire oxidizes as fast you try to clean it.
very difficult to handle without oxidization
