Conventional current

  1. Jul 27, 2008 #1
    My text shows current flowing from negative to positive, and also uses the right hand rule to get the B-field this way. I always thought convention was to flow from positive to negative, and also the b-field followed this convention as well. Any comments?

    As I recall, the convention is that current will flow from negative to positive while potential (voltage) will flow from positive from negative.

    Current always flows from positive to negative voltage, unless it's within a voltage source. And voltage (or potential) doesn't "flow" at all. It's a fixed quantity in time-invariant circuits.
