Full wave rectifier with capacitor filter
Click For Summary
Discussion Overview
The discussion revolves around identifying components and sections of a full-wave rectifier circuit, including the roles of various elements such as diodes, capacitors, and transformers. Participants seek clarification on terminology and the structure of the circuit.
Discussion Character
- Homework-related
- Technical explanation
- Conceptual clarification
Main Points Raised
- One participant expresses difficulty in identifying the names of components in a full-wave rectifier circuit.
- Another participant describes a full-wave rectifier circuit as consisting of an AC source, a transformer, diodes (2 or 4), and a capacitor in parallel with a resistor.
- A different participant suggests that the circuit includes an AC section and a DC section, but notes that a clearer image is needed to provide more specific information.
- There is a mention of using a resistive load versus a capacitive filter to achieve different output voltages from the rectifier.
- Some participants question whether the inquiry is related to homework and discuss the need for research on the topic.
- One participant shares a link to an external resource that provides information about full-wave rectifier circuits.
Areas of Agreement / Disagreement
Participants generally agree on the basic structure of the full-wave rectifier circuit but express uncertainty regarding specific component names and the exact configuration without a clearer image. There is also a debate about whether the inquiry is homework-related.
Contextual Notes
Some participants indicate that a clearer image of the circuit would help in identifying the components and their connections more accurately. There is also a lack of consensus on the specific terminology used for different parts of the circuit.

Hi Ahmed22. http://img96.imageshack.us/img96/5725/red5e5etimes5e5e45e5e25.gif
My spectacles seem heavily fogged up this morning. But from memory a full-wave rectifier circuit comprises an AC source feeding a transformer, then either 2 or 4 diodes, and followed by a large capacitor in parallel with a resistor (the resistor representing the load).
If it needs 4 diodes then it's usually referred to as a bridge rectifier, and it delivers full-wave rectification.

See; http://en.wikipedia.org/wiki/Electronic_symbol
The mists of time also cloud my judgment.
My guess is that you have an AC source followed by a transformer, then a bridge rectifier, a storage capacitor and a resistive load.

The first part is the AC circuitry. The second half is the DC circuitry. Without a focussed image we really cannot guess at what joins the two parts.

It is probably showing an alternative load: you can operate the rectifier with a resistive load, or you can operate it with a large filter capacitor across that load. You get greater load voltage (i.e., greater average or DC output voltage) by using the capacitive filter.

WOW. What did you search for? I looked up "full wave rectifier circuit" with google and the first link described everything.
