Resistance boards: Series, parallel, Wheatstone bridge.

Resistance boards: Series, parallel, Wheatstone bridge.This demonstration can be used to show voltage and current relationships in series and parallel resistance networks (Ohm's Law and Kirchoff's Law). Voltage is supplied with a two 6 Volt batteries, and various resistance values can be chosen (.5,1,2,3,4 & 5 k ohms, variable Potentiometer, short, 12v bulbs, etc.) A number of plug-in boards are available (including a Wheatstone's Bridge).
