That is correct. Since potential difference is a difference, Vb - Va ,then you can have all three possibilities. The potential at a point, say Va, is itself a difference. It is the potential difference between point "a" and a second point "0" where the potential is choosen to be zero. This zero point is completely arbitrary , provided it does not lead to mathematical difficulties. Sometimes it is convienient to choose a zero location for potential and sometimes its not necessary. For example; suppose the potential difference between charged parallel plates a & b is Vb - Va = 10 volts. This would require that Vb > Va , but the actual values of Vb & Va need not be known. Then Va - Vb = - 10 volts. If one wants to choose point "a" as the zero point, then Vb = 10 v. Or if one wants to choose Vb as the zero point then Va = - 10 v. Or if one wants to choose midway between the plates as the zero point then Vb = 5v & Va = - 5v.
Negative numbers are below zero whereas positive are above zero.
No.
Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.Zero is not negative. It is not positive either.
No, not counting zero,the difference is always positive since minus a minus is plus
If you mean the difference in terms of numerical value, then it is the positive faction minus the negative faction, which is calculated as the positive fraction plus the absolute value* of the negative fraction - just like the difference between a positive and negative number. * The absolute value of a number is the value of the number ignoring any minus sign; eg abs(-4) = 4 = abs(4). If you mean the difference in terms of where they are on the number line, then the positive fraction is one side of zero (it is greater than zero) and the negative fraction is the other side of zero (it is less than zero).

im not sure how clearly your phrasing your question, but when dealing with circuits potential difference (voltage) is max, and at the positive terminal its zero. it decreases as you go around the circuit. hope this helps
There is no negative of zero, nor is there a positive. Zero is no value, hence it has no positive or negative value.
Positive and negative whole numbers and zero are integers. Zero is neither negative or positive.
There are just three possible cases: Positive integer: positive x positive = positive. Negative integer: negative x negative = positive. Zero: zero x zero = zero.
Zero is neither positive or negative.
You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.
