= 2.3 mA
1 kΩ At time t = 0+, we treat the C as a voltage source of 0V and the L as a
current source of 2.3 mA. (The switch is also open, removing the 2.3 V
source and 1 kΩ resistor from the circuit.) We can solve the circuit for
any voltage or current at t = 0+. Using Kirchhoff's laws for voltage loops
and current sums at nodes, we have the following results, (with voltages
measured with plus on top, and currents measured flowing in the down
direction): v R (0+ ) = v L (0+ ) = vC (0+ ) = 0 V v (0+ )
iR (0+ ) = C
100 mΩ € iC (0+ ) = −iR (0+ ) − iL (0+ ) = 0 A − 2.3 mA = −2.3 mA € Now we are ready to find A1 a...
