Voltage regulation
3
What does the following circuit do?
It is a voltage regulator with a 5.1V output
It is a rectifier circuit
It amplifies the input voltage
It is a voltage regulator with a 12V output
4
What does the following circuit do?
It is a voltage regulator
It turns both cycles of the input signal into a positive voltage
It is a half wave rectifier which removes one half of the input signal
It amplifies the output signal
5
Name the following components
OpAmp, Transistor, Zener diode
Transistor, OpAmp, Rectifier diode
Diode, OpAmp, Transistor
Zener diode, transistor, OpAmp
6
How would the ouput signal change for a silicon diode instead of an ideal one?
The peak voltage would be higher
The peak voltage would be lower
The ouput wave would be wider
The output wave would be narrower
7
What would happen to the output if we added a capacitor in parallel to the load resistor?
The peak voltage would increase
The output signal would be the same as the input
The capacitor would add a "smoothing" effect to the output signal.
It would not change anything
