Coulomb’s Law Sample Data

Please set the output voltage of the power supply to about 2-3V with the switch in open position.

To slow down the battery discharge, the switches should be closed only when reading an LCR meter; otherwise keep the switches open.

Functioning batteries should put out a minimum of 5 V for the 6-V ones and 10 V for the 12-V ones when measured in the closed circuit (with the switches closed).
