1.
Three capacitors C
1
= 3 μC, C
2
= 5 μC, and C
3
= 8 μC are each charged by a 24

V battery and then
connected as shown.
a)
Determine the final charge on
each capacitor
b)
Determine the potential between points X and Y
2.
An aluminum plate of thickness
L
and area
A
is slid into a parallel

plate capacitor of plate spacing
d
and area
A
, as shown. The aluminum is a distance
x
from one of the plates. What is the capacitance
of this arrangement?
Leave your answer in terms of
A, d
and
L
.
3.
A cylindrical capacitor has an inner conductor of radius 1.5 mm and an outer conductor of radius 3.5
mm. The two conductors are separated by vacuum, and the entire capacitor is 2.8 m long.
a)
What is the capacitance per init length?
b)
The potential of the inner conductor is 350 mV higher than that of the outer conductor. Find the
charge (magnitude and sign) on both conductors.
