Question about the sign of output voltage in clipper circuits
Click For Summary
Discussion Overview
The discussion revolves around the labeling of voltage terminals in clipper circuits, particularly in relation to sinusoidal and DC inputs. Participants explore how to determine the positive and negative signs for the terminals based on the input voltage conditions.
Discussion Character
- Conceptual clarification, Debate/contested
Main Points Raised
- One participant expresses confusion about how to label the terminals in a clipper circuit when the input voltage is positive or negative, referencing their professor's labeling method.
- Another participant suggests that the image provided clarifies the behavior of AC current, though no specific details are given.
- A later post reiterates the confusion, questioning whether it is possible to label the terminals oppositely when the input voltage is positive, especially if the circuit is flipped.
- One participant introduces a hypothetical scenario involving DC input, asking what the output would be for specific positive and negative voltage values.
Areas of Agreement / Disagreement
Participants do not appear to reach a consensus on the labeling of terminals in clipper circuits, with multiple viewpoints and uncertainties expressed regarding the correct approach.
Contextual Notes
There are limitations in the discussion regarding the assumptions made about the circuit orientation and the definitions of positive and negative voltage in different contexts.

sorry for the post, it isn't complete, i was interrupted by my classmates while typing.
Here's the continuation:
What I'm actually trying to ask is how do i label the positive and negative signs. I can't express myself clearly in English so i'll just give the situation: My professor labels the upper terminal in the input side as + and the lower terminal as - when the input voltage is positive and when the input is negative, the positive and negative signs are reversed. how do i know how to label the terminals when the input is positive or negative. I'm confused because, if i flip over the circuit, doing the opposite is also valid...

Just to clarify my question: Vin in the image I've given is positive and my professor has labelled the upper terminal in the input as + and the lower labelled as -. When the input is negative the + sign goes down and the - sign goes up.
Is it not possible that the when Vin is positive, the upper terminal is - and the lower is +.
If i flip the circuit backwards, this is the result.

Assume that the input is DC instead of AC.
If the input is +20V what is the output?
If the input is -20V what is the output?
If the input is +20V what is the output?
If the input is -20V what is the output?
