The voltage (V1) that feeds the t-line and returns through the 100 Ω lamp is a 1 volt step. The end of the t-line is shorted: -- 
- Points to note: -
- - Immediately the t-line acts like a 600 Ω line and immediately some current (1.429 mA) is passing through the lamp. This is important because it basically tells you that the daft video is er... daft.
- - After some time has passed, the current eventually rises in steps to a value of 10 mA (1 volt / 100 Ω).
