Batteries vent Hydrogen gas. You should always connect the positive battery cable first to avoid a spark at the battery that could cause the Hydrogen to explode. The negative cable should never be connected to the battery negative post. It should be connected to another ground area on the engine.
What else can I help you with?
Can i charge 6 volt batteries in series with a 12 volt charger?
Yes you can. Make sure the batterys are hooked together in SERIES and not parallel !!! Be sure the batterys have the correct amount of fluid in each cell to prevent "cooking " a cell.yes - the batteries must be connected together on series and the charger must be connected to one batterys pos. terminal and the other batterys neg. terminal
When an ammeter is connected in a circuit which terminal of the battery must be connected to the positive terminal of the ammeter?
The positive terminal of the battery would be connected to the positive terminal of the ammeter. The load would then be connected between the two negative terminals, positive side of the load being connected to the negative side of the ammeter.
When you charge a car battery what do you disconnect first?
When charging a car battery, you should always disconnect the negative terminal first. This helps prevent any short circuits or sparks that could occur if the positive terminal is disconnected first while the battery is still connected to the car's electrical system. After charging, reconnect the positive terminal first before reconnecting the negative terminal.
How do dry cell batterys work?
when it works it has copper sulfate solution inside the wet cell battery which takes the electrodes from the negative terminal (-) to the positive terminal (+).
Which terminal of bulb does connect with battery?
Center terminal is connected to the positive from the battery. Outside is connected to ground (-).
Why do you not get battery symbol on your laptop sometimes after you on power supply in your laptop made by Toshiba model no A200?
Note: When interconnecting A200 batteries (cells), they must be identical in voltage and amp rating! Batteries may be connected in series. The positive terminal of the first battery is connected to the negative terminal of the second battery; the positive terminal of the second is connected to the negative of the third, and so on. The voltage of the assembled battery is the sum of the individual batteries. The batteries are connected: + to - to + to - to + to -, etc. The capacity of the battery is unchanged. Batteries may also be connected in parallel. The positive terminal of the first battery is connected to the positive terminal of the second battery, the positive terminal of the second is connected to the positive of the third; the negative terminal of the first battery is connected to the negative terminal of the second battery, the negative terminal of the second is connected to the negative of the third and so on. The batteries are connected: + to + to + and - to - to -. In this configuration, the capacity is the sum of the individual batteries and voltage is unchanged.
What does forward bias on a diode?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
Is the positive terminal of an ammeter connected to the positive terminal of the energy source?
No. An ammeter is to be connected in series, between the device and the battery's positive output, Its NEGATIVE terminal (red lead) has to be connected to the POSITIVE of the battery. Its positive terminal (black lead) will then be connected to the device's positive terminal. (Connecting an ammeter in series with a power supply by itself may damage or destroy the meter.)Almost every single digital ammeter made will indicate reverse current, so the worst you might get is a displayed reading of a negative amperage if you connected it in reverse.(For an illustration, see the related link)
What does forward bias on a diode means?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
Copper from impure copper has to be transferred to the pure copper which one has to be connected to the positive terminal?
If it is electrolysis you are talking about, I'm fairly confident the impure copper has to be connected to the positive terminal.
When a dry cell is connected in a series the flow of electrons moves from the positive or negative terminal to the positive or negative terminal?
When a dry cell is connected in a series, the flow of electrons moves from the negative terminal to the positive terminal. Electrons are negatively charged particles and are attracted to the positive terminal while repelled by the negative terminal. This movement creates an electric current that flows through the circuit.
What is the meaning of straight and reverse polarity?
Straight polarity refers to the welding setup in which the electrode is connected to the positive terminal and the workpiece is connected to the negative terminal. Reverse polarity is the opposite setup, with the electrode connected to the negative terminal and the workpiece connected to the positive terminal. These polarity settings affect penetration, heat distribution, and weld quality in different ways.
