Default Derivation of Reflection Coefficient vs SWR

I disagree. If the current through the 50 ohm source resistor is
0.039216, then the power in the 50 ohm source resistor cannot be
0.03845w. Namely because 0.039216 * 0.039216 * 50 = 0.076895w
(eye-squared-are, matey). Either your power is wrong or your current is
wrong. My own calculations show that your current is correct. Therefore,
your energy analysis appears to be in error.


You seem to have forgotten that since 0.039216 is the maximum
value of current you need to divide the 0.076895w by two.



Yes, I forgot to use the RMS value of the source.
