Question

I Am having trouble sovling H8P1,,,,,
Can someone please help with what formulas are used and how to find
(a) What is the value of vR1(t) at t=0− in Volts (V)?
(b) What is the value of vR1(t) at t=0+ in volts (V)? Hint: Recall that that ∫0+0−δ(t)dt=1
(c) What is the value for vR1(t) at t=1ms in volts(V)? (Hint: The L-R1 and C-R2 branches of the circuit are decoupled.)
(d) What is the value of vC(t) at t=0+ in volts (V)?
(e) What is the value for vC(t) at t=1ms in volts (V)?

Answer 1

I have found that at t=0-, voltage of capacitor and Inductor is 0, can't figure out the rest of question.

Answer 2

H8P1 IMPULSE

a) 0
b) 2000
c) 270.6706
d) 3030.3
e) 146.3667
