Key Terms

Transmission Line
A conductor or conductors used for transmitting electrical energy.

Example: High voltage transmission lines carry electricity over long distances.

Impedance
The total opposition a circuit offers to the flow of alternating current.

Example: Impedance combines resistance and reactance.

Voltage Drop
The reduction in voltage in the electrical circuit between the source and load.

Example: Voltage drop can affect the performance of electrical devices.

Power Loss
The energy lost as heat in electrical components.

Example: Power loss in transmission lines can be calculated using P = I²R.

Load Flow
The analysis of power flow in electrical networks.

Example: Load flow studies help in determining voltage levels at different points.

Reflection Coefficient
A measure of how much of a wave is reflected by an impedance discontinuity.

Example: A high reflection coefficient indicates poor matching.
