How Do You Calculate Input Currents and Load Voltage in a Transmission Line?

AI Thread Summary
To calculate the input currents I+ and I- in a transmission line with given parameters, one must first apply the transmission line equations. The input impedance Z_in, the characteristic impedance Z0, and the input current i_in are crucial for determining the forward and reflected currents. The voltage at the load can be derived using the relationship between current, impedance, and voltage across the transmission line. It is essential to show relevant equations and initial calculations to receive further assistance. Properly setting up the problem will facilitate accurate solutions.

Z in =50-j10 Ohms
i in=2 amps
length = 2 meters
Z0=75 Ohms
u=2E8 meters per second
beta=.3 rad/m

How do I find I+ and I- at the input?
What is the voltage at the load?

Any help would be appreciated.
