The switch has been in position a for a long time. At t=0 ms, the switch moves to
position b. At t = 5 ms, it moves to position a. At t = 10 ms, it moves to position b.
a) What is the RC time constant $\tau_b$ for the period from 0 ms to 5 ms? $\tau_b$ = 
b) What is the RC time constant $\tau_a$ for the period from 5 ms to 10 ms? $\tau_a$ = 
c) $V_c(t)$ =
