Given a lightning stroke profile as in Figure Ass 2.4 and the line reactance at 50 Hz of 0.015 Ω, the lightning stroke profile is estimated as follows:

- a negative edge rising to -23 kA in 5 μs;
- a falling edge decaying to zero in 1005 μs.

a) What is the induced-voltage profile in the line due to the lightning strike?

b) Sketch the approximate waveforms of the lightning strike current and induced voltage on the line.
