A negative DC source could be connected in such a way as to act as a positive DC source. I'm not sure why you would want to flip it - supplying power "the wrong way" could cause equipment failures, protective systems (such as fusing) to not provide protection, and general other bad things.
I am not sure what exactly you mean, but some devices will be damaged if polarity is reversed.
The voltage adds if you connect in series (positive to negative). It stays the same if in parallel (Positive to Positive and Negative to Negative).
A: actually it is the other way around usually negative voltage is a biasing scheme. Most design are begun with a positive voltage in mind. Not that a negative voltage will not work it is just people think positive
The term, 'negative voltage', refers to its direction and has nothing to do with 'negative' in the 'charge' sense. It's used to indicate the direction in which a voltage is acting in relation to another voltage ('positive' if acting in the samedirection; 'negative' if acting in the opposite direction). So your question is confusing: 'negative' in relation to what?
Negative voltage is voltage that is more negative in polarity than the ground of the circuit.AnswerSince 'voltage' is simply another word for 'potential difference', it can be neither negative or positive in the 'charge' sense! These terms can only be applied to 'potential', not to 'potential difference' (voltage).So, the terms 'positive' and 'negative', when applied to voltage, simply indicate sense or direction in which the potential difference is acting. For example, if you decide that a car battery's voltage is acting in the 'positive' sense in the charging circuit, then the alternator's voltage must then be acting in the 'negative' sense -in other words in the opposite direction to the battery.
could be negative or positive"negative logic" just means, that the level used by "positive logic" within that logic family for False, is instead used for "True" and vice versa.
the meanings of positive and negative voltage

Is called AC voltage or current.
A positive DC voltage is an electric potential where excess electrons will flow from negative to positive.AnswerYou appear to be mixing up potential difference (i.e. voltage) with potential. There is no such thing as a 'positive' voltage if you mean 'positive' in the sense of charge! 'Voltage' means 'potential difference', and you cannot have a positive or negative potential difference in this sense. You can only apply positive and negative in this sense to potentials.However, if you mean 'positive' in the sense of direction, then a positive voltage is one that is acting in the opposite direction to a negative voltage within the same circuit. For example, where two batteries have been connected in opposition.
First connect the positive terminal of the voltage line to positive terminal of multimeter and negative to negative terminal of multimeter. Select voltage in multimeter and measure the voltage
Positive clipper-the clipper which removes the positive half cycles of the input voltage, while the negative clipper the clipper which removes the negative half cycles of the input voltage.
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
A cell with a negative voltage charge.
Voltage dividers can provide anything between VCC (the most positive voltage in the circuit) and VSS (the most negative voltage in the circuit). For example, if VCC =0 and VSS = -15, then the output voltage has to be negative. ========================
