How It Is Used
A DC supply such as a battery eliminator is connected and the switches set for series, then for parallel. From the voltage and current readings students calculate the equivalent resistance each way and compare it with the values worked out from the individual resistors, checking Kirchhoff’s voltage and current laws.
