The following are the correct sign conventions for analyzing circuits using Kirchhoff's Laws EXCEPT: For travel direction from negative to positive terminal, the emf should be positive. For travel direction from positive to negative terminal, the emf should be negative. For travel direction opposite to current direction, the voltage drop across the resistor should be negative. For travel direction same as the current direction, the voltage drop across the resistor should be negative.
