Steady state before t = 0. At t=o

the switch opens.

a) Draw the circuits before and after the switch opens.

b) Find the initial voltage of the capacitor, the initial

current through the capacitor, the initial voltage

across the 25-52 resistor, the initial current through.

c) Find the rate of change of the capacitor voltage,.

In what way does the rate of change depend on

the voltage itself? In what. do the capacitance.
