I have a wierd question I think... I'de like to know how low a frequency and how high a current can a wireless device transmit. eg, radio frequency is over 1000s of Hz, can it be much lower than that?When you recieve a radio signal to an antenna, a small current is generated which is interpreted as sound. How high can that current be? If there's no limit to the amperage generated at the recieving end, how can you calculate it? 10x!
