Full Wave Rectifiers Quiz

What is the working principle of a full wave rectifier?

• Converts only one half of the input AC signal into DC output

• Converts both halves of the input AC signal into DC output

• Converts the input DC signal into AC output

• Does not convert the input signal at all

Explain how a full wave rectifier converts AC to DC.

• It uses a square wave circuit to convert AC to DC

• It uses a parallel circuit to convert AC to DC

• It uses a bridge circuit to convert both halves of the AC input signal into a pulsating DC output.

• It uses a half wave circuit to convert AC to DC

How does a bridge rectifier circuit work?

• By using a capacitor to convert AC voltage into DC voltage.

• By using four diodes to convert AC voltage into DC voltage.

• By using three resistors to convert AC voltage into DC voltage.

• By using a transformer to convert AC voltage into DC voltage.

What are the components of a bridge rectifier circuit?

• Five diodes

• Two diodes

• Three diodes

• Four diodes

What is a center-tapped rectifier circuit?

• A type of rectifier circuit that uses a single diode

• A type of full-wave rectifier circuit that uses a center-tapped transformer

• A type of AC voltage regulator circuit

• A type of half-wave rectifier circuit that uses a center-tapped transformer

How does a center-tapped rectifier circuit differ from a bridge rectifier circuit?

• They differ in the number of terminals on the transformer.

• They differ in the type of transformer or diode configuration used.

• They differ in the type of cooling system used.

• They differ in the color of the components used.

What are the advantages of using full wave rectifiers?

• No change in efficiency and ripple

• Lower efficiency and more ripple

• Higher cost and complexity

• Higher efficiency and less ripple

How does a full wave rectifier provide better efficiency compared to a half wave rectifier?

• It uses both halves of the input signal.

• It has a higher ripple frequency.

• It has a lower output voltage.

• It uses only one half of the input signal.

What are the disadvantages of full wave rectifiers?

• Limited applications, not suitable for high power

• Higher cost and complexity, requires center-tapped transformer

• Lower cost and simplicity, does not require a transformer

• Less efficient, produces more ripple

Explain the issue of higher cost associated with full wave rectifiers.

• Full wave rectifiers require more components such as diodes and transformers, leading to higher cost.

• Full wave rectifiers have longer lifespan, leading to higher cost

• Full wave rectifiers have lower efficiency, leading to higher cost

• Full wave rectifiers use less components, leading to higher cost
