Description:
Unknown Resistance Board
Specification:
Unknown Resistance Board -Expand upon the concepts taught by the Wheatstone Bridge (615-4540).
Assign each group a different "unknown", which are "disguised" so their
value cannot be read. Our compact device features nine 1% resistors from
1 to 100 kiliohm, randomly mounted on a printed circuit board, any two
of which can be connected in series. The resistors are wired in such a
way that over 360,000values can be found. Each 1/4 watt resistor
survives direct application up to 12 volts. Includes instructions.
