Electromagnetics lossless transmission line problem Typed so

Electromagnetics lossless transmission line problem. Typed solution preferred. Please answer and label part clearly and solution should not be too long.

A lossless transmission line with 75 ohm characteristic value is terminated by an unknown load ZL. If at the input of the line, which is 51.3 from the load, we know that the value of the total voltage is 20 volts and the value of total current is 0.4 amperes Find I at the input Cind the load impedance Find V and I at the load

Solution

load impedance= total voltage /total current

= 20/0.4

=50 ohms.
