What is impedance matching in the context of transmission lines?

• Reducing the voltage of the transmission line to match the load or source

• Adjusting the impedance of a transmission line to match the impedance of the load or source

• Changing the color of the transmission line to match the load or source

• Increasing the length of the transmission line to match the load or source

What are the primary sources of transmission line losses?

• Resistance in the conductors, dielectric losses, and radiation losses

• Friction in the conductors, magnetic losses, and convection losses

• Voltage drop in the conductors, insulation losses, and corona losses

• Capacitance in the conductors, inductive losses, and skin effect losses
