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

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.

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.

Charging a dead car battery?

To charge a dead car battery, you'll need a compatible battery charger or jumper cables and another vehicle with a working battery. If using a battery charger, connect the positive terminal of the charger to the dead battery’s positive terminal and the negative terminal to a grounded metal point on the car. If jump-starting, connect the positive terminals of both batteries first, followed by the negative terminal of the working battery to the dead battery's negative terminal. Allow the dead battery to charge for a sufficient time before attempting to start the vehicle.

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.

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.

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.

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.

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.

How can i get 16 volts from two 8 volt batteries?

To obtain 16 volts from two 8-volt batteries, connect them in series. This involves connecting the positive terminal of the first battery to the negative terminal of the second battery. The remaining free terminals (the negative terminal of the first battery and the positive terminal of the second battery) will provide the combined voltage of 16 volts. Ensure that both batteries are of the same type and capacity for optimal performance.

Should you connect both ends of a battery in a circuit?

Yes, both ends of a battery should be connected in a circuit to create a continuous flow of electric current. When one end of the battery is connected to one terminal of a component and the other end to the other terminal, a closed circuit is formed, allowing electricity to flow and power the device.

What is the difference between a 24 and a 24f battery?

The primary difference between a 24 and a 24F battery lies in their terminal configurations. A 24 battery typically has its positive terminal on the left side when the terminals are facing you, while a 24F battery has the positive terminal on the right side. This difference in terminal placement can affect compatibility with certain vehicle models, so it's essential to choose the correct type for your application. Both batteries are similar in size and capacity, but the terminal layout is crucial for proper installation.
