charge is within, and "wipe" the charge onto the
inner surface of the cup.
•
Use the relationships given below to calculate the
charge that has been transferred.
•
For a capacitor of capacitance C, the relationship
between the charge Q and the voltage U is:
= ⋅
Q C U
•
Since U = U , the output voltage from the
OUT IN
electrometer gives a measure of the charge Q :
= ⋅
Q U C
OUT
•
The capacitor U8403501 has the known capacitance
C = 10 nF, and therefore the charge can be
calculated.
