  3. 3. Describe how a capacitor filter smoothes out a rectified voltage, and explain how the value of the filter
    capacitor determines the amount of ripple voltage.

    use a zener diode for voltage regulation (line regulation and load regulation).

    (calculate) voltage gain, input resistance, and output resistance of an amplifier.
