Why do a bulb light up when both ends of a battery are attached to the same battery terminal?

because when you connect the both end of the battery to the same battery terminal, it is called a parallel connection, therefore when it's parallel connection the ampere rating of the battery increases, so it's enough that would able to light up the bulb,. .hope my answer would help,. hehehe^_^

If you have a thick wire attached to the positive terminal of a battery attached to a light bulb attached to a thin wire of the same length will the current be the same in both wires?
Yes; the current will be zero, because--as described--the wires are not connected in such a manner as to create a circuit.
I can't get my car out of park now because when I replace the brake light bulb a fuse blows - what am I doing wrong?
Try disconnecting the positive feed to the battery terminal. Then replace the bulb and fuse, once both are done, reconnect the battery.
What drains the battery on an 86 Ford Escort?
There is an easy way to find out what is draining the battery on your car. Disconnect the positive or negative battery terminal. Not both. Connect a test light between the post of the battery to the cable end of the battery. If your car is draining the batt ery the light will show it. To find out where the drain is coming from just pull fuses until the light goes out. Then you will know what is draining the battery by the function of the fuse you just pulled. For example, if you pulled the fuse for "radio" and the light went out you would know the radio is drawing the current off your battery.
What will happen if one battery terminal is connected to a terminal?
Nothing. An auto battery system is 12V DC. If both terminals aren't in the loop (positive through the current path and back to negative) nothing happens.
Positive car battery terminal gets too hot to touch is that normal?
No, Remove the terminal and clean with wirebrush until both the clamp and battery post are shiny.Re-install.The heating problem should be eliminated.
Your alternator and battery both tested good but the battery is not being charged?
Most likely cable running from stud on top of alternator to battery terminal is corroded or broken.
How do you wire up a ammeter?
In general, an ammeter needs to be installed between the device providing electricity and the device(s) using electricity. This kind of connection, where you break the wire and install the meter across the break, is called a "series" connection. In an automobile, the ammeter should be installed in the smaller of the two positive (usually red) battery cables, the one that runs from the positive battery terminal to the alternator charging terminal (and also to rest of the non-starter electrical loads). Here is a simple drawing: B+ ------(\)---------- A+ ---------- ACC ST Where: (\) = The Ammeter B+ = Positive Battery Terminal A+ = Alternator Charging Terminal ST = Starter (large cable) ACC = To vehicle Accessories (small cable) i.e., ignition, lights, etc. ------ = smaller (typically 10 gauge) red wire = larger battery/starter cable (typically 4 gauge or larger) Notes: * Do not install the ammeter in the large cable that goes to the starter. * The small cable from the Alternator to the battery may be attached to the battery terminal, or it may be attached to the starter terminal. Electrically these are equivalent. * In order for the ammeter to properly show whether the battery is charging or discharging, the ammeter must be installed between (a) the battery and (b) both the alternator and fuse block/ignition switch. * If the accessory cable is also attached to the starter, it will have to be removed and attached to the alternator side of the ammeter or to the alternator as shown in the drawing. * Make sure you disconnect the negative battery terminal before working on the electrical system. ALWAYS wear safety googles whenever working on or near the vehicle battery.
Should you connect both ends of a battery in to a circuit?
The circuit won't do anything until both terminals of the battery are connected to the correct [two different] points in the circuit. As long as either terminal of the battery remains disconnected, the circuit is "OFF".
Do you have a diagram on 9volt battery and light bulb?
Draw a battery and light bulb. Draw a line from the smaller connector on the battery to the bottom of the light bulb, this is positive on both. Draw a line from the bigger connector on the battery to the side of the light bulb,'this is the negative of both. Looked all over and can't seem to find this one.
What color is Car battery positive terminal?
Both posts are gray, positive has a red wire running to it, and a plus sign next to it.
Dose the positive battery terminal hook to solenoid in a 1985 f-150 inline 300 6cylinder?
Positive Battery Cable Routing on F-150sI'm not familiar with your '85 model, but I have both an '89 and a '93 F-150 with the same 4.9L/300 straight six engine. On both of my vehicles, the cable from the Positive terminal of the battery goes to the input [always "hot"] terminal of a solenoid mounted on the right front inner fender. A similar heavy cable goes from the solenoid output [ignition switch controlled] terminal to the starter.There are also lighter conductors that go from the hot input terminal of the solenoid to the vehicle's electrical system.
How do you reset service engine soon light for a 1997 Chevy blazer?
take your battery cables OFF of the battery. Make sure BOTH cables are disconnected from the battery! touch the Red cable terminal to the black terminal. AGAIN make sure the battery is NOT hooked up to any cables! There will not be any spark or anything. You will see nothing happen. The only thing this is doing is discharging some caps in your ECU. When you hook everything back up to the battery and start the truck the light will be off. The truck may run a little bit different for the first few drives. This is normal because you reset your ECU your truck has to "relearn" some things.
