Why does an "L pad" impedance-matching network bear that name?

Because the network employs one or more inductors, elements that are traditionally abbreviated with the symbol "L."

Because it is similar to a launch pad in terms of the large amount of power throughput enabled by a favorable impedance match.

Because the two resistors in the network are traditionally oriented in the shape of the capital letter "L" on schematic drawings.

Because it was named in honor of Hendrik Lorentz, an early electromagnetic theorist.

Answer & Explanation

Correct Answer: Because the two resistors in the network are traditionally oriented in the shape of the capital letter "L" on schematic drawings.
