Electrons flow from negative to positive. But everything in nature moves from higher potential to lower potential, i.e the charges should move from positive to negative but they don't?
Look up again the definition of potential. You will see that is defined by using a positive charge as probe. So "low" and "high" potential according to standard definition are valid for a positive charge. If we use a negative charge, the low and high will change places. But rather than doing this re-definition we say that negative charges move from low to high potential.Elsa1234 said:Electrons flow from negative to positive.

Quite true. Electrons 'fall down' to the positive terminal (opposite sign) and their potential energy reduces. If, originally, early electrical Science had chosen a different sign for the charges, when electrons were found. they would have been given a Positive charge and this particular problem would not have presented itself to students. OTOH, the important principle that's involved, could have passed them by without them noticing.Geofleur said:objects have to move toward lower potential energies.
Electrical current is the flow of electric charge through a conducting material, such as a wire. It is typically measured in amperes (A) and is represented by the symbol "I".
Electrical current is created when there is a difference in electric potential, or voltage, between two points in a circuit. This difference causes electrons to flow from the higher potential to the lower potential, creating a current.
Electrons are subatomic particles that have a negative charge. They are one of the fundamental components of an atom and are responsible for carrying electrical current through a material.
Electrons move in a circuit by being pushed by an external electric field, created by a voltage source, such as a battery. They flow from the negative terminal of the source to the positive terminal, completing the circuit.
According to Ohm's Law, the relationship between electrical current and resistance is inversely proportional. This means that as resistance increases, the current decreases, and vice versa. This relationship is represented by the equation I = V/R, where I is current, V is voltage, and R is resistance.
