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.

Why the dc average voltage is having negative value?
Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.
How does emergency light switch work?
An emergency light switch uses a relay. A relay has an 5 terminals. The firs two terminals are connected to a flowing current (current flows when there is a normal electricity) The next 3 terminals are the common, the normally on, and normally off. One of the battery terminal is connected to the common, and the other one terminal of the battery is connected to one terminal of the light bulb(which has two terminals) then the other terminal of the light bulb is connected to the normally on terminal of the relay. When current flows to the first two mentioned terminals of the relay, the circuit of the battery and light is cut off or not connected. But when the current is off, this will switch on the normally-on terminal thus current will flow from the battery to the light bulb, that will shed light. ;) on an emergency situation. note: The normally off is not use. And may be use for some purpose.
Why is a diode called unidirectional?
A diode is unidirectional because of the diode only conduct in forwardbias .As you know the diode have two terminal cathode and anode . and when the positive terminal of battery connected to the p-side and other terminal connected to the other terminal of diode then diode is called forward biased . and when it connection is just opposite then it become in reverse biased . so we can finally say that the diode is unidirectional
What is terminal PD?
A terminal potential difference is the potential difference appearing across the terminals of a voltage source, such as a battery or a generator, which varies according to the load supplied.When the battery or generator is off load (i.e. no load is connected to it), the terminal potential difference is equal to the electromotive force of that battery or generator.The terminal potential difference tends to decrease as the load current increases, due to a corresponding increase in the internal voltage drop of the battery or generator.
In an electric circuit why do the electrons go from the positive side of the battery to the negative side?
The short answer is that they don't. But that doesn't help you much. Electrons flow from the negative terminal to the positive terminal. Why? Negative and positive (opposite) charges attract each other, and like charges repel each other. So you can think of the positive charged end pulling electrons towards it, as well as the negative charged end pushing electrons away from it. Water makes a good analogy, the battery is a pump, so there is high pressure on the outlet of the pump ( the negative terminal ) through the pipes and whatnot, ( the wire and whatnot) to the inlet of the pump ( the positive charged end ).
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?
when the positive terminal of the battery is connected to the positive terminal of the diode it is said to be in forward bias
Why the positive terminal of an ammeter is connected to the positive terminal of battery?
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.
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.
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.
