5 Questions
Question 1 of 5
In a common-emitter amplifier, the output signal is 180 degrees out of phase with the input signal. What is the main reason for this phase inversion?
The collector current is inversely proportional to the base current, causing the phase shift.
Question 2 of 5
What is the primary function of a capacitor in a power supply filter circuit?
Capacitors store charge during the peak voltage and release it during the valleys, smoothing the output.
Question 3 of 5
Which of the following is NOT a typical application of an operational amplifier (op-amp)?
Op-amps are primarily analog devices; digital logic typically uses dedicated gates.
Question 4 of 5
What is the purpose of a zener diode in a voltage regulator circuit?
Zener diodes maintain a constant voltage across them when reverse biased within their breakdown region.
Question 5 of 5
In a diode full-wave rectifier, how many diodes are typically used?
A full-wave rectifier requires four diodes to rectify both halves of the AC cycle.
