What is sign of voltage flowing positive to negative electrical circuit?

Voltage is also known as Potential Difference
There are two main sign conventions to remember
Let me tell u in a simple manner
1) In a circuit when take a part of a loop where the component cell is present then if we move from the +ve to the -ve terminal then the sign should be the last one that is the negative sign
In the same way if we r moving from -ve to the + ve terminal then the sign should be plus+
2) Now if consider the resistor
When we move in same direction of the flow of current then the sign is minus(negative)
When we move in the opposite direction of the flow of the current then the sign is plus(positive)..
Hope my answer is helpful to u

Let’s start by defining positive electric current as this:
1. Positive electric current is the movement of positively charged particles.
OK, well at positive terminals, say the + end of a battery, there is a net positive charge. So positive charge will be moving from the positive end to the negative.
Now let’s say we defined negative current similarly:
2. Negative electric current is the movement of negatively charged particles.
Now, the current will flow from negative to positive. So at the negative terminal, there are a whole bunch of electrons (negative charge carriers) that will be flowing from negative to positive.
As it turns out, protons (which are the primary positive particles) are huge and don’t like to flow much, so electrons (which are MUCH [about 2000 times] smaller) are the particles that generally make up the electric current. So the direction of the positive current is just opposite the direction of the electron flow; there aren’t really many positive charges flowing in the direction of the positive current.
Unfortunately, several centuries ago Ben Franklin defined current as the flow of positive charges. Or that’s the story, anyways. So now, that’s what we call conventional current - the flow of positive charges. But remember that it’s opposite the direction of the electron movement.
