Data Harvest

Product Description

 

A replacement for the traditional gold leaf electroscope. 

Allows the quantity of charge and polarity to be recorded and not just the presence of charge.

 


1-minute on Charge sensor: measuring a static charge

Additionally the sensor can function as a very high resistance (at least 10 to the power of 12 Ohms), accurate voltmeter. Six ranges, 3 for different charge intensities and 3 for voltage. Ideal for measuring charges developed by rubbing acetate, polythene or ebonite rods. 

Teaching applications:

  • Magnitude and sign of the charge on different objects
  • Electrostatic phenomena
  • Simple demonstrations of sign of charge
  • Charge sharing between conductors
  • Faraday’s ice pail investigations
  • Electrostatic shielding
  • Induced charge
  • Charging by induction
  • Density of charge on the surface of a conductor
  • Investigating the relationship ‘Voltage is proportional to the charge on an object’ by adding charges
  • Measuring emf of cells
  • Measuring voltages of half cells
  • Discharge of a capacitor

Determine the sign of charges  
Using a charge sensor we can go further than the electroscope and show both the magnitude of the charge and the sign of the charge. A big step up form electroscope work.

Adding charges 

Activity to show that charges can be added to a collecting surface.

Leaking charges 
We are always told that charges leak away due to the permettivity of air and point discharge loci. But how how much does leak away?

Faradays Ice Pail 
Investigate the charges on a Faraday's ice pail. Using the Charge sensor you can see magnitude and sign of the charges collected and induced.

Charge from movement 
Watch charges being built up as you move around! fun activity and also good for explaining how the wrong trousers can create an explosion!
