Why might an ammeter give a negative value for current? (HINT: Part of a current’s measure is the velocity of its electrons. Why would a velocity be negative?)
velocity of electrons can't be negative but here one thing you must remember that current does not flow in the direction of electrons movement it always flows in the opposite direction to the electrons.because electrons always go from negative terminal to positive terminal whil currentt always flow from positive terminal to negative terminal.
I hope you understand
