Half-Wave Rectifier

Front

What is a half-wave rectifier?

Back

A half-wave rectifier converts AC to DC by allowing only one half-cycle of the AC waveform to pass through, blocking the other half.

Front

What are the fundamental components of a half-wave rectifier?

Back

Transformer, Diode, Load Resistor (RL).

Front

What is the role of the transformer in a half-wave rectifier?

Back

A step-down transformer reduces the high AC voltage to a lower, more manageable AC voltage for the circuit.

Front

How many diodes are used in a half-wave rectifier?

Back

A single p-n junction diode.

Front

What is the function of the load resistor (RL) in a half-wave rectifier?

Back

It is the device or circuit that receives the rectified DC output.

Front

How does the diode operate during the positive half-cycle of the AC input?

Back

The diode is forward-biased, conducting current through the load.

Front

What happens to the diode during the negative half-cycle of the AC input?

Back

The diode becomes reverse-biased and blocks the current.

Front

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

Back

A pulsating DC voltage that contains a significant amount of ripple.

Front

What is the output voltage across the load during the positive half-cycle?

Back

The output voltage mirrors the positive half of the AC input waveform.

Front

What happens to the output voltage during the negative half-cycle?

Back

The output voltage is zero as no current flows through the load.
