What is the main function of a diode in a circuit?

• Amplify current

• Store charge

• Allow current in one direction

• Convert DC to AC

A half-wave rectifier uses how many diodes?

• 2

• 1

• 3

• 4

What type of output does a half-wave rectifier provide?

• Pure DC

• Pulsating DC

• AC

• Constant AC

Which component is used to smooth the output of a rectifier?

• Inductor

• Capacitor

• Resistor

• Transformer

When is a diode forward-biased?

• When it blocks current

• When it allows current to pass

• When voltage is zero

• Always

What does a capacitor do when the input voltage increases?

• Charges

• Discharges

• Blocks current

• Inverts the voltage

What happens to a charged capacitor when the input voltage drops?

• Charges more

• Discharges slowly

• Short-circuits

• Does nothing

Adding a capacitor in a rectifier circuit results in:

• Increased AC noise

• Voltage reversal

• Smoother DC output

• No effect

What is the output of a capacitor-filtered half-wave rectifier called?

• Pure AC

• Smoothed DC

• Reverse current

• Amplified signal

• AC

• DC

• Pulsating DC

• Filtered DC
