Problem Four (7.5 pts, 2.5 pts each part)
In the circuit shown below, the output voltage of the rectifier passes through two filtering stages; the first is a C-filter ($C_1$) while the second is an RC-filter ($RC_2$). $R_L$ is the load resistance. The voltage $V_1$ is given as follows:
$V_1 = 12 + 1.2 \sin(377t)$
If $R_L = 10 \text{ k}\Omega$ and $R = 1 \text{ k}\Omega$, answer the following:
1) What is the peak-to-peak ripple in Volts and the ripple as a percentage in the voltage $V_1$?
2) What is the value of $V_2$?
3) Explain the impact of increasing the value of $C_1$ on the average output voltage and the voltage-ripple across the load resistance?
