How much power is being absorbed by the load when a directional power meter connected between a transmitter and a terminating load reads 100 watts forward power and 25 watts reflected power?
Pick an answer to check it.
Answer: D. 75 watts
Power absorbed by the load is forward power minus reflected power. P = 100 W - 25 W = 75 W.
Tip: Load power = forward minus reflected.
