WebMay 10, 2024 · The amount of electricity a radio will use depends on its power rating. The power rating is defined in Watts. In general a smaller AM/FM radio will use 1 watt per hour, whereas bigger digital radios will use up to 5 watts. Again, these numbers will vary depending on the radio’s power ratings. WebMar 9, 2015 · It's also worth mentioning that the power of an AM signal is: - P T = P C ( 1 + M 2 2) where M is the index and Pc is unmodulated carrier power This basically means that a 100 watt carrier modulated by an index of 0.5 results in a power of 112.5 watts.
