In the test report of electric energy meter, there will be cos φ=0.5C or 0.5. What do l and c mean here respectively?
L stands for inductance, that is, current lag voltage, and c stands for capacitance, that is, current lead voltage.

Cos φ=0.5L represents the current lag voltage 60, that is, the power factor =0.5L,

Cos φ=0.5C indicates that the current leads the voltage by 60, that is, the power factor =0.5C..
