Question 1
1 pts
A test capacitor with a capacitance of 23.67pF is used to determine the capacitance of an
electrometer. If the initial voltage reading from the electrometer is 26.99V and the final
voltage is 18.5V after the test capacitor is applied, determine the the electrometer
capacitance in pico-Farads.
Question 2
3 pts
If a electrometer with a capacitance of 90.86pF reads a voltage of 27.14V from a circular
parallel plate system with a plate separation of 0.04cm, determine the charge of the
system if the disk diameter is 17.7cm. Express the charge in pico-Farad * Volts.
Question 3
3 pts
A DMM reads a reference capacitance of 4.3pF while unconnected. After connecting one
end of the DMM to each side of the circular parallel plate system with an unknown
material in the middle, the DMM reads a capacitance of 136.4pF. The disk diameter is
given as 16cm with a unknown material thickness of 3mm. Determine the dielectric
constant.
