While this is a non mathematical and general descriptive treatment of the subject it is a challenge to make it clear and consistent. I know this group has some expertise on this subject and would appreciate any constructive comment and suggestions regarding the attached article. http://members.optushome.com.au/vk6ysf/vk6ysf/radio.htm Thank you for your time. Regards Peter VK6YSF Albert Einstein is frequently quoted saying: "The wireless telegraph is not difficult to understand. The ordinary telegraph is like a very long cat. You pull the tail in New York, and it meows in Los Angeles. Here is the drawing of the cat: http://library.thinkquest.org/18160/electriceasy.htm The wireless is the same, only without the cat." There is a small difference. If instant of the cat (wire) is an insulator (aether) in it flows the displacement current. The current is strong when the capacitance and the frequency is big. It is easy to achive the huge frequency but for this you must use the modulation. S* |
