The circuit below contains a capacitor of capacitance
C
, a power supply of emf
, two resistors of resistances
R
_{1}
and
R
_{2}
, and two switches,
S
_{1}
and
S
_{2}
.
Initially, the capacitor is uncharged and both switches are open. Switch S
_{1}
then gets closed at time t = 0.
(a) Write a differential equation that can be solved to obtain the charge on the capacitor as a function of time
t
.
(b) Solve the differential equation in part (a) to determine the charge on the capacitor as a function of time
t
.
Numerical values for the components are given as follows:
= 12 V
C = 0.060 F
R
_{1}
= R
_{2}
= 4700
(c) Determine the time at which the capacitor has a voltage 4.0 V across it.
After switch S
_{1}
has been closed for a long time, switch S
_{2}
gets closed at a new time t = 0.
(d) On the axes below, sketch graphs of the current I
_{1}
in R
_{1}
versus time and of the current I
_{2}
in R
_{2}
versus time, beginning when switch S
_{2}
is closed at new time t = 0. Clearly label which graph is I
_{1}
and which is I
_{2}
.
