Mag Posted July 15, 2005 Posted July 15, 2005 (I think this is the right place to put this) Ok, so i have a TV in my room, and whenever its on and i put my hand or something near it, you can hear static electricity. So, sometimes i put the TV on to play some games, and i have a Portable CD Player in my hand. Then i put the CD player on top of the tv, and the earphone wire hangs down, getting close/touching the screen - i can usually hear the static when it does that. This time though, i did the same thing, but the static was louder, and my CD Player turned off. I never learned Electricity in physics So i was wondering, how was there enough from the TV to turn off the CD player? First time its ever happend. Thanks
YT2095 Posted July 16, 2005 Posted July 16, 2005 the On/Off on many of todays digital equipment is no longer a hardwired Switch, it`s often controlled by Logic. these logic levels and the chips that use them often work in micro-amps, and so a spurious voltage on a line can easily "trip" a Logic 1 state to a logic 0 state, thus turning the device off, sometimes it can do other things depending on the application. I have a radio in my shed, it has a sleep and wake-up function on it, when I key up on my Sideband transmiter at anything above 5 watts, it turns itself off too
