Homework Help: Direction of current flow

  1. Apr 9, 2007 #1
    1. The problem statement, all variables and given/known data
    I'm much too confused about direction of flow of current.Conventionally, it's said that flow of charge is due to +ve charge carriers & high potential end of battery being +ve & low potential end being -ve,current flow will be from positive(high) to negative (low) terminal.But in case of electric current when flow of current is due to electrons (-ve charge carriers) what'll become of high & low ends.Should'nt we say that high potential terminal is -ve & low potential is positive because it's electron deficient?.In simple terms my confusion is:
    "If electronic circuit is due to electron flow ,are they flowing from high (-ve) to low(+ve) terminal?

    2. Relevant equations


    3. The attempt at a solution

    we all are confused. With metallic wires, electrons carry charge, but in other instances positive ions, carry current. So we decide that by convention, positive charges are the current carriers, knowing well this isn't true. BUt the math comes out the same for simple physics.
