Purely
Inductive Load |

|
|
Here is an example of a purely inductive load, which results in a pure
standing wave on the line, like a short or open circuit. |

Voltages for an Inductor Load |

Note: |
- All reactive components produce a reflection coefficient of
|G|=1. The only difference between and
inductor or capacitor load is that a different phase offset is
introduced at the end of the line. Notice how, for this example,
the voltage standing wave ends on the load side at neither a peak nor
a null.
|
- It should make intuitive sense that the inductor (or capacitor)
has a unity reflection coefficient. Since ideal inductors (or
capacitors) are simply energy storage devices, there is no place to
sink power at the load for a long period of time. Thus, all
power sent down the line must be returned to the source at steady
state.
