In a DC circuit must the positive and negative conductors be the same size if not how is the size difference determined?

Yes, since the current is the same through out the complete circuit. the design size of the conductor entering the circuit should be the same size as the conductor leaving the circuit.

What is a positive DC voltage?
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.
Should positive go to positive in a circuit?
No, this will not work. Postitive to Negative/Negative to Positive will work.
Why the dc average voltage is having negative value?
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.
How can you get negative voltage?
Your question should read "How do you get a negative potential?", for the reasons explained below.The term, 'voltage', is another word for 'potential difference'. The terms 'positive' and 'negative', when applied to a potential difference or voltage indicates the sense (or direction) in which the potential difference or voltage is acting. For example, if a second voltage is acting in the same direction as another voltage then it is acting in the positive sense; if it is acting in the opposite direction then in is acting in the negative sense'.It's very important to understand that you cannot apply 'positive' and 'negative' is the sense of charge or polarity to potential difference or voltage. You can, however, apply these terms to 'potential'. Potential is relative, and always measured with respect to a given point (often, the earth). So a point can be, for example, +5 V or -5 V with respect to another point (usually earth or ground, but not necessarily).Never confuse 'potential' with 'potential difference' and remember that 'voltage' means potential difference notpotential.So, to obtain a negative potential, earth (ground) the positive terminal of the battery or d.c. supply. All potentials measured relative to earth are now negative. To obtain a positive potential, earth the negative terminal of the battery or d.c. supply instead. All potentials measured relative to earth are now positive.If you want to get a negative potential,Earth the positive terminal of the DC power sourceConnect a resistor in series with the negative terminal of the sourceAt the other end of the resistor you get a negative potential (the value's less than the value of the power supply)
Is there a difference between black wire and red wire?
Yes, the red wire is a positive wire (+) and the black wire is a negative wire (-) :D
Is determined a negative connotation?
No it is a positive connotation.
Is the difference of a negative integer and negative integer always a positive?
No, because if the positive was 8, and the negative was -4, the difference would be positive four.
Is the difference of a positive integer and a negative integer always negative?
No, because if the positive was 8, and the negative was -4, the difference would be positive four.
When you are subtracting a positive integer from a negative integer Will the difference be positive or negative?
positive
Will the quotient determined by two negatives be a positive or negative value?
Positive.
Is the difference of a positive integer and negative integer always a positive?
No, a positive minus a negative can be either or positive or a negative.
What is the difference about positive and negative?
negative is below zero, positive is above
Is the difference of a negative and positive always negative?
no

What are the Difference between positive and negative development?
one is positive, the other is negative
What is the difference between a negative and a positive?
positive ions carry positive charge and negative ions carry negative charge
What characteristics of sound is determined by amplitude?
The strength or volume of sound. By increasing the amplitude you enlargens the energy because the difference between peak negative and peak positive voltage in the waveform gets bigger. One use positive and negative voltage so that a loudspeaker can Push and Pull the membrane. Amplitude is the difference between Negative and Positive. IE Wave Bottom and Wave Top.
