5A22.93 - Electroscope - FET

Code Number:
Demo Title:
Electroscope - FET
Electrostatic Deflection & Detection
Area of Study:
Electricity & Magnetism
FET Electroscope with 9 volt battery, positive and negative charging rods.

Video Credit: Jonathan M. Sullivan-Wood.

Plug a 9 volt battery into the battery clip of the FET electroscope.  Bring a negative charge near the sensing gate and the red LED will come on. A positive charge will make the green LED come on.
