Understanding Full Wave Rectifiers

What is the basic configuration of a full wave rectifier circuit?

• Four diodes in a bridge configuration connected to an AC source.

• One diode connected directly to a battery.

• Three diodes in a parallel configuration connected to an AC source.

• Two diodes in a series configuration connected to a DC source.

Draw the circuit diagram of a full wave rectifier using diodes.

• The circuit diagram uses a single diode connected directly to the AC source with no additional components.

• The circuit diagram consists of four diodes (D1, D2, D3, D4) arranged in a diamond shape, with the AC input connected to the top and bottom points, and the DC output taken from the left and right points.

• The circuit diagram consists of two diodes arranged in series with the AC input connected to one end and the DC output taken from the other end.

• The circuit diagram features six diodes arranged in a parallel configuration with the AC input connected to all diodes.

Calculate the output voltage (Vout) for a full wave rectifier with an input voltage of 10V (peak).

• 8.2V

• 6.37V

• 4.5V

• 12V

What is the frequency of the output signal in a full wave rectifier if the input AC frequency is 50Hz?

• 50Hz

• 200Hz

• 25Hz

• 100Hz

Explain the difference between a full wave rectifier and a half wave rectifier.

• A half wave rectifier uses only one half of the AC signal, while a full wave rectifier uses both halves.

• A half wave rectifier can only be used with positive signals, while a full wave rectifier can handle negative signals.

• A full wave rectifier uses only one diode, while a half wave rectifier uses multiple diodes.

• A half wave rectifier converts AC to DC without any loss, while a full wave rectifier has higher losses.

What is the peak inverse voltage (PIV) in a full wave rectifier?

• The PIV is equal to the average voltage of the AC input signal.

• The PIV is the RMS voltage of the AC input signal.

• The peak inverse voltage (PIV) is equal to the peak voltage of the AC input signal.

• The PIV is half the peak voltage of the AC input signal.

Calculate the average output voltage for a full wave rectifier with a peak input voltage of 12V.

• 10.50V

• 9.00V

• 7.64V

• 5.00V

List two applications of full wave rectifiers in electronic circuits.

• Oscillator circuits

• Amplifier circuits

• Voltage regulation circuits

• Power supply circuits, Signal processing circuits

How does the output waveform of a full wave rectifier look compared to the input waveform?

• The output waveform is a series of positive peaks, with no negative portions, compared to the input AC waveform.

• The output waveform is identical to the input waveform.

• The output waveform has both positive and negative portions like the input.

• The output waveform is a flat line with no variation.

What is the role of the transformer in a full wave rectifier circuit?

• The transformer converts DC voltage to AC voltage.

• The transformer regulates the output current of the circuit.

• The transformer filters out high-frequency noise.

• The transformer steps up or steps down the AC voltage and provides isolation.
