Proto-Hack Challenge: October

Halloween Edition!

Hack together "handheld fire" for your Halloween costume in a few easy steps.

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance,[1]one arrives at the usual mathematical equation that describes this relationship:[2]
I = \frac{V}{R},
where I is the current through the conductor in units of amperesV is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.[3]
