Suggested Activity
Use the Charge Sensor to demonstrate the
magnitude of charge build-up induced on PASCO
Charge Producers (ES-9057A).
In this demonstration, you connect the Charge
Sensor to a Faraday Ice Pail (ES-9042A) as shown
in Figure 2.
After setting the sensor up in your data acquisition
program and opening a Meter display, briskly rub
the Charge Producers together. Next, lower one of
the Charge Producers into the inner basket of the
Faraday Ice Pail.
Result: The magnitude of the charge that was
provided when the Charge Producers were rubbed
together will be displayed on the Meter display.
The Charge Producer with the blue surface will
acquire a negative charge, and the one with the
white surface will have a positive charge. The
magnitude of the positive and negative charges will
be equivalent.
