Purpose:Shows L/R time constant for a slow circuit
Description:A nine-volt battery is used to energize the LR circuit while the current through the LR system is observed on an oscilloscope. The system is then shorted and allowed to de-energize. This setup uses an approximately 6 kilohenry coil and about 12 kilohms series resistance to produce a time constant of about 1/2 second.
