AP Free Response Question
2008 C2 E&M
In the circuit shown above, A and B are terminals to which different circuit components can be connected.
(a) Calculate the potential difference across R
_{2}
immediately after the switch
S
is closed in each of the following cases.
i. A 50 Ω resistor connects A and B.
ii. A 40 mH inductor connects A and B.
iii. An initially uncharged 0.80 μF capacitor connects A and B.
(b) The switch gets closed at time t = 0 . On the axes below, sketch the graphs of the current in the 100-ohm resistor R
_{3}
versus time t for the three cases. Label the graphs
R
for the resistor,
L
for the inductor, and
C
for the capacitor.
