Question

why positive terminal has high potential energy and why nagetive terminal has low potential energy​

Answer 1

Answer:

The mass gains gravitational potential energy. If the positive charge moves from the positive terminal to the negative terminal then the force is attractive and the charge loses potential energy. ... So for electron flow, the positive terminal is lower potential energy.

Answer 2

Answer:

1. The positive terminal is at the high potential, and that potential causes positive charges to flow from high potential to low potential. ... It would have been "better" to define electrons to have a positive charge and flip the terminals of the battery.

Explanation:

2.Now, for positive charge to flow from the negative terminal of a battery to the positive terminal work must be done because the force is repulsive. This increases the potential energy of the positive charge. ... So for electron flow, the positive terminal is lower potential energy.
