Use this set of nine unknown resistances to work with your Wheatstone bridges.

  • Connect in series or parallel

Each resistor has a unique resistance, but all are 1/4 watt metal film with 1% accuracy. Resistances start with 1.21 KΩ to protect against overloads and range up to 90.9 KΩ at no particular interval. They are mounted visibly underneath a printed circuit board with connections through binding posts on top; the resistors are numbered 1 to 9.
