Question

Can you do the PSpice? Thank you

2) Refer to the handout and use the series RC circuit in Fig. 1 Analytically solve the capacitor current and voltage outputs.Explain the circuit operation by interpreting the equations Use PSpice to obtain the transient responses of the voltage and current signals (Hint: Check the "Sw tOpen" "Sw tClose" components and Transient" setup option). Use PSpice to compare the effects of the R and C values on the transient response. To do this part, you need to use sweep function in PSpice (Hint: Use a VPULSE' source and set TR and TF properly. Define R and C as global parameters by using "Param" component and define the component variation in the "Parametric" "Global Parameter" setup options).Qualitatively, how do the R and C values change the responses? a. b. e.

Answer 1

We know, V_C (t) = V(infinity) + [V (0^-) - V (infinity)] e^-t/RC given V(0^-) = 0 V ckt at t = infinity \r\n T = Req Ceq = [10 + 1000] * 1 times 10^-9 T = 1.01 mu s therefore V_c (t) = 5(1 - e^-990 times 10^3 t) Volts therefore i-e (t) = c dvc(t)/dt i_l (t) = 4.95e^-990 times 10^3 t mA
