How do you differentiate inductive loadcapacitive load resistive load which basics?

For an inductive load, the current lags the voltage by 90 degs. Hence the power factor for an inductive load is 0. For a capacitive load, the current leads the voltage by 90 degs. Hence the power factor for a capacitive load is 0. For a resistive load, the current and the voltage are in phase. Hence the power factor for a resistive load is 1.
