We know there's a wireless signal that comes from a tower to the receiver to the device. However, we're learning about electricity, and one of my students wants to know what sort of current powers all this stuff. We've talked about static electricity and current electricity. To be quite honest, this is simply something I'm not sure I can answer for him. I realize that current electricity powers the tower that sends the signal, but how can a signal provide electrical anything?
It's plugged into a surge protector that I forgot to turn off while working on the electricity. I had to turn the circuit breaker on and off a few times, and now it's not giving off a wireless signal. The regular cable modem that came with my internet is saying it has a signal, but my computer isn't getting a signal and the little light on the wireless modem is a solid color instead of flashing. I've tried resetting it and unplugging it for 20 seconds at a time, but still nothing. Is it broken? Or do I just need to leave it unplugged longer? Thanks! Witricity: explain witric..
