The proper polarity has to be adhered to so as to make the meter's needle deflection move in the correct direction. The wrong polarity will deflect the needle in the opposite direction and pin the needle against the needle stop on the left side of the meter's scale. This could un-calibrate the ammeter and the readings would not be accurate if this happens.

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.


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)


Which terminal of bulb does connect with battery?

Center terminal is connected to the positive from the battery. Outside is connected to ground (-).


How do you use an ammeter?

The Positive side of the Ammeter should be connected to the positive side of the battery and the Negative side should be connected to the Globe/Conductor/Insulator to provide a valid reading.


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.


Why is it important to connect the positive lead of the ammeter to the positive side of the battery?

The ammeter will only read when connected properly. If the meter is connected backwards, then the meter reads the wrong way. If it is a digital ammeter then it may not work at all.


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


What does forward bias on a diode means?

Can you charge a 12 volt battery with a 24 volt charger?

I can if I charge 2 of them at a time. Most 24 volt chargers also have a 12 volt setting. What is hard to find is a 32 volt charger. We can charge a 12V battery with 24V charger, by connecting two 12V batteries in series i. e. the negative terminal of the first battery is connected to the positive terminal of the second, now the charger positive terminal is connected to the first battery positive terminal and the negative terminal of the charger is connected to the negative terminal of the second battery.


What are positive ground cars?

Cars in which the positive terminal of the battery is connected to the chassis. They require specially designed components built for positive ground cars. The usual configuration is a negative ground (the negative battery terminal connected to the car's chassis).


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.


The positive terminal of a dry cell battery identifies the location of the carbon rod?

The positive terminal of a dry cell battery typically identifies the location of the carbon rod, which acts as the positive electrode in the battery. When the battery is connected in a circuit, it is the positive terminal that attracts electrons from the external circuit, facilitating the flow of current within the battery.
