Problem 1: Question
After having been in position 2 for a long time (circuit reached steady state), the
switch in the circuit below was moved to position 1 at t=0 s.
E₁
15 V
Determine
2
1
R₂
13 ΚΩ
www
R₁
12 ΚΩ
C₁₂
0.9 μF
a) ic1 (t=0-) and vc1(t=0-), i.e. just before the switch changes positions (just before
t = 0 s)
b) ic1(t=0) and vc1(t=0), i.e. just after the switch changes positions
c) ic1(t=co) and vc1(t=∞0), i.e. at steady state after the switch changes positions
d) The expression for vc1(t) for t≥ 0 s
