Understanding Diodes and Rectification

What is the primary function of a diode?

• To amplify signals

• To convert AC to DC

• To store electrical charge

• To increase voltage

What is another name for a diode?

• Transistor

• Resistor

• Rectifier

• Capacitor

In half-wave rectification, what happens to the AC waveform?

• Only the negative half is retained

• The waveform is inverted

• Both halves are retained

• Only the positive half is retained

What is the result of using a diode in a circuit with AC?

• The current flows in both directions

• The current flows in one direction only

• The current is amplified

• The current is stored

What is the main disadvantage of half-wave rectification?

• It requires a large number of components

• It cannot convert AC to DC

• It results in a non-steady DC

• It is too expensive

What component is used to smooth the current in a rectified circuit?

• Diode

• Transistor

• Capacitor

• Inductor

How does a capacitor help in smoothing the current?

• By increasing the voltage

• By amplifying the current

• By storing and releasing charge

• By converting AC to DC

What happens to the charge in a capacitor during reverse bias?

• It is amplified

• It is released

• It is stored

• It is lost

What is the final result of smoothing the current with a capacitor?

• A steady DC similar to a battery

• A non-steady DC

• An amplified AC

• A reduced voltage

What is the process of using a capacitor to create a steady DC called?

• Rectification

• Amplification

• Smoothing

• Inversion
