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.

You can say DC voltage has a frequency of zero Hz.Because it is unidirectional in nature (may be positive or negative)
luo converter is a new technique adopted for dc to dc voltage lifting(dc voltage boosting)...
DC
It is the process of conversion of generated ac voltage into the armature of a dc generator to dc voltage at the terminal of the dc generator by use of pair of brushes and commutator. OR It is the process of conversion of given dc voltage at the terminal of the dc motor to ac voltage in the armature windings in a dc motor by use of pair of brushes and commutator.
A 9V DC (direct current) supply can be either positive or negative, depending on how it is configured. Typically, in most applications, a 9V DC source is positive, meaning the positive terminal has a higher voltage relative to the negative terminal. However, if the terminals are reversed, it can be considered a negative 9V DC. The designation of positive or negative is determined by the polarity of the voltage applied.
This DC voltage is called the DC offset. Any decent signal generator will be able to add DC offset to the signal it generates. If you don't have one, simply connect a DC voltage to your signal.
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.
If the positive probe of the oscilloscope is connected to the negative terminal and the negative probe is connected to the positive terminal of a DC supply, the oscilloscope will display an inverted signal. This means that the voltage reading will be negative, effectively showing the opposite polarity of the actual DC voltage. The magnitude of the reading will remain the same, but the trace on the oscilloscope will appear flipped around the zero voltage line.
It travels from negative to positive. The opposite of what you might think.
Bipolar dc involves both majority carrier and minority carriers for conduction while unipolar requires only majority carriers or minority carriers during conduction. point of view based on electronics devices.

In a DC circuit, the direction of current flow is from the positive terminal of the voltage source to the negative terminal.
No, if you measure positive voltage to ground, the meter will show a positive voltage reading. In this case, the meter will indicate the positive voltage difference between the measured point and ground, not a negative voltage value.
There is only 1 type of DC voltage, and that is direct current. In order to better answer your question, you need to be more specific.
get a multi meter that reads dc voltage & touch the black (negative -) wire to the negative battery post & the red (positive +) wire to the positive battery post with car running. car off is battery voltage, car on is alternator voltage.
