Ham radio transmitter power
http://arrl.org/frequency-allocations Webpower: P = E x I. From our question we know that E = 400 volts. However, we are not provided any information on the current (I). Rather, we have been provided the resistance of the load, 800 ohms. Aha! Check out the Ohm’s Law relationship, I = E ÷ R. We can substitute E ÷ R for I in the Power Law relationship! So, it goes like this:

In amateur radio, QRP operation refers to transmitting at reduced power while attempting to maximize one's effective range. QRP operation is a specialized pursuit within the hobby that was first popularized in the early 1920s. QRP operators generally limit their transmitted RF output power to 5 Watts or less regardless of mode be it CW operation or SSB operation.
