A generator is connected to a short-circuited line 1.25 wavelengths long.

(a) Sketch the waveforms for the incident, reflected, and resultant voltages at the instant the generator is at its maximum positive voltage.

(b) Sketch the pattern of voltage standing waves on the line.

(c) Sketch the variation of impedance along the line. Be sure to note whether the impedance is capacitive, inductive, or resistive at each point.
