1. Calculate the capacitance between nodes (a,b).
2. The graph below shows the voltage applied to a 5
μ
F capacitor as a function of time.
(a) Derive expressions for the current flowing into the capacitor for
t
=
0 . . . 3 ms,
t
=
3 . . . 8 ms,
and
t
=
8 . . . 9 ms.
(b) Derive expressions for the power delivered to the capacitor as a function of time.
(c) Derive expressions for the energy stored on the capacitor as a function of time.
(d) Plot the results from parts (a) to (c).

3. The capacitor is initially discharged (
v
o
=
0 V). Assume that the opamp is ideal. Accurately
plot the value of
v
o
(
t
)
for the source voltage shown below. Calculate the voltage at each break
point.
