How do we find the point of higher voltage in a circuit?
There was a physics exercise in which there were 2 points A and B on a circuit and between them was a resistor. The question was which one is at higher voltage. How do we find that? Is it the point towards which the current flows?

Whichever point, A or B, is connected to (or is nearest to) the positive side of the battery, is at the highest voltage (potential).
The voltage is largest at the positive side of the battery and gets less as you work around the circuit to the negative side of the battery.
Conventional current flows from high to low potential. (But the electron flow is from low to high potential because electrons are negative.)

Using the "water analogy" of electric flow, wouldn t it be the point from which the current flows? i.e. the current flows from a point of higher voltage to a point of lower voltage.
