Electrical Engineering/Electronics: Battery Holder & 9V Snap Connector

AI Thread Summary
The discussion centers on the user's confusion regarding the functionality of a battery holder and a 9V snap connector. The battery holder outputs 6V when tested, but initially did not work with the 9V snap connector. After troubleshooting, including cleaning connections and using alligator clips, the user successfully connected the snap connector to the battery holder, resolving the issue. It was suggested that the problem may have been due to poor contact or a short circuit. The user expressed gratitude for the assistance received in clarifying the situation.

Hey everyone,

I just went to Radio Shack and picked up a few parts to begin a book on Electrical Engineering/Electronics. I'm taking it slow and trying to understand the theory behind everything before I progress - something simple has got me confused though.

I have two parts:
The battery holder is putting out an expected 6V when I test with a multimeter. However, it is putting out no voltage with a 9V snap connector. The 9V snap connector does produce voltage when connected to a single 9V battery. Is there a reason I can't use this connector here? I couldn't find much information regarding this question on Google. Thank you in advance!

There's nothing in the connectors that will make any distinction between 6V and 9V. They are just dumb pieces of metal. I would guess that it is physically making contact somewhere that it shouldn't. Maybe the wires are being shorted out, etc.
 
Since connecting to the battery holder gave me no read, I decided to connect the snap connector via alligator clip test leads. This measured 6V, as you said it should. All in all, I pulled around on the wires and cleaned the connections and managed to get it to work with the 9V snap connector directly to the battery holder. It seemed to be a fluke of some sort, confusing my newbie mind. Thank you for the quick help!
 
Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.)
