Question
Can someone solve the following problems for me? IGNORE PROBLRM #7
Given a circuit, shown below for t 0 assuming that the switch is closed at t = 0. Additionally, determine the final value of the voltage across the capacitor (i.e. steady state value ... as t rightarrow infinity). Implement/Simulate the circuit in the above in MULTISIM. Replace the voltage sources depicted in the above circuit with an equivalent pulse voltage source. Perform a transient analysis with the switch closed and deduce/measure the rise time of the circuit by making use of the cursors. Submit a screen shot of your simulation (showing the circuit, Grapher View and measurements/cursors). Your name should appear on the circuit .Compare the measured rise time to the one that you calculated/found in problem 6. For the circuit below: Given the following Cartesian/Rectangular form of impedances:Explanation / Answer
using thevenin's theorem the circuit can be simplified to normal RC circuit
Vth=(R1+R5)/(R1+R5+R6) *V1 [V2 and V3 cancels out]
=(7/13) *12 V
=6.46V
Rth=R2+[R6||(R1+R4)]
90+5*8/(5+8) kOhm
=93.08 kOhm
For RC circuit
time constant=RC=93.08 k*250 *10^-6=23.27sec
rise time=1.386*Time constant=32.25 s
Voltage across capacitor at T->infinite is -6.46V
8)1/z1=11+22j/sqrt(11^2+22^2)=0.447+0.89j
1/z2=9-14j/sqrt(9^2+14^2)=0.54-0.84j
1/z1+1/z2=0.987+0.05j
1/(1/z1+1/z2)=0.987-0.05j/sqrt(0.987^2+0.05^2)=0.999-0.05j
zs=z3+z4=12-24j+25+17j
=37-7j
