Problem
Why is the originally chosen direction of conventional current still followed in circuit analysis today?
(a) Because electrons actually flow from the positive terminal to the negative terminal, so current is defined that way.
(b) It maintains consistency of sign conventions and equations established historically.
(c) Because metals have only mobile positive charges that drift toward the negative terminal.
(d) Because reversing the convention would make Ohm's law V=IR incorrect.
