What is the PEP produced by 200 volts peak-to-peak across a 50-ohm dummy load?
Pick an answer to check it.
Answer: B. 100 watts
200 V peak-to-peak is 100 V peak. RMS = 100 x 0.707 = 70.7 V. PEP = E^2 / R = 70.7 x 70.7 / 50 = 5,000 / 50 = 100 W.
Tip: P-P to peak (/2), to RMS (x 0.707), then E squared / R.
