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!
 
While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
