Connect a $12$V source, a $100$k$$ resistor, and an open switch in series with a leaky capacitor having C $=5$F and R $=2$M$.$ The switch closes at t $=0.$

$($a$)$ Draw this circuit.

$($b$)$ Determine the capacitor voltage as a function of time.

$($c$)$ After a long time, the switch is opened again. What is the voltage across the capacitor $10$

blem $9.$ Consider the following model of a $$leaky$$ capacitor. If there is a small current through the capacitor even when it is fully charged, we can model it as an ideal capacitor C in parallel with a very large resistor R$.$
