Why should a car battery's positive terminal be connected first for charging?

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.

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.
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.
What does the positive side of the battery do?
When connected to the cable which normally runs to the starter it completes the circuit. Electrons flow from the negative terminal to the positive terminal.
Is a zinc anode acts the terminal?
No. It seems Zinc would always act as the negative terminal. Anode and Cathode are the terms used when we connect an external electrical source to the device. If positive terminal of an external battery is connected to the electrode then that electrode is named as ANODE. If negative terminal is connected then it is named as CATHODE. In case of chargable device, while discharging say P acts as negative terminal. Then while charging this negative terminal would be the anode. So if the device is a chargable one and Zn acts as negative terminal while delivering current to the external load, then the same zn would acts as anode while charging.
What are the differences between a parallel circuit and a series circuit?
in parallel circuit passive components such as resistor capacitor and inductor are connected in such away tht all components positive sided terminals are connected together and similarly negative sided terminals. and then positive terminal of the source is connected to positive side and vice versa.while in case of series circuit negative terminal of first component is connected to the positive terminal of the second component and so on and then source is connected
