A transmission line 1,500 km long is initially under steady-state conditions, with potential 1,200 Volts at the source at x=0 and 1,000 Volts at the load (x=1500). The terminal end of the line is suddenly grounded due to a short, reducing its potential to zero while the potential at the source is kept at 1,200 Volts. Find the potential along the transmission line at any time t. Assume negligible inductance
