5E40.15 - Human Battery

Code Number:
Demo Title:
Human Battery
Chemical Storage of E.M.F.
Area of Study:
Electrically & Magnetism
Copper and Magnesium Electrodes, Voltmeter, and Aluminum Electrode if Desired.

Plug the electrodes into the voltmeter.  Orientation does not make a difference.  Set the voltmeter on 2 VDC.  The copper and magnesium electrodes should give about 1.4 volts when touched with one hand on each electrode.  The copper and aluminum electrodes will only give about 0.5 volts.
