In a series RLC circuit containing a resistor, an inductor and a capacitor the source voltage V S is the phasor sum made up of three components, V R, V L and V C with the current common to all three. Since the current is common to all three components it is used as the horizontal reference when constructing a voltage triangle.
In capacitive circuits, voltage lags current, as shown in Figure 3. Greater amounts of time between current and voltage peaks indicate a greater amount of inductive or capacitive load, and either condition increases the work needed to deliver the required amount of real power to loads.
