1) The switch has been open for a long time when at time t = 0, the
switch is closed. What is l, (0), the magnitude of the current through
the resistor R1 just after the switch is closed?
A Submit
2) What is 1 (~), the magnitude of the current that flows through the
resistor R1 a very long time after the switch has been closed?
A Submit
3) What is Q(*), the charge on the capacitor after the switch has been
closed for a very long time?

4) Consider the circuit above, with R5 = 89 N
in series with the capacitor. Once again,
the switch has been open for a long time
when at time t = 0, the switch is closed.
