It depends on the configuration of the ammeter. If you have an ammeter with red on one side, green on the other, and a balance point in the center, the needle will go into the red when when load is increased in relation to the charge. If the load is decreased in relation to the charge, the needle will go into the green.
If you have an ammeter with a numerical value (i.e. 30, 40, 50, etc.) then the needle will go up to the value of the load present in the system not in relation to the charge.

When measuring with an ammeter the ammeter must be connected in?
When measuring a load current, an ammeter is connected in series with the load. The exception is for a clamp on style AC ammeter, which is clamped around one of the conductors, making its measurements as a transformer.
What happens to the ammeter reading when a lamp is added to a circuit which contains two cells and a lamp in series?
Assuming the new lamp is in series, the ammeter reading falls because the total resistance has increased. By how much depends on how the lamp resistance depends on voltage. If the lamp is added in parallel to the first, then the ammeter reading doubles.
Which circuit the ammeter connected in parallel?
An ammeter is always connected in series and a vlotmeter in parallel
How is ammeter and voltmeter attached to a circuit?
Ammeters are connected in series with the load under test. This requires the load be disconnected from the source, and the ammeter placed in circuit. Voltmeters are connected in parallel with the load under test. This does not require any circuit changes. Sorry, but WikiAnswers does not support illustrations.
What instrument can you use to measure reactive power of a load?
An ammeter and a wattmeter are the instruments needed.
What happens to the reading on an ammeter if the value of a variable resistor is increased?
it explodes and burns everyone in the room.
Why is ammeter connected in series with the load?
A ammeter will tell you how much current draw the load is drawing
How do you connect a ammeter into a circuit?
connect ammeter in series with load.
How ammeter connected?
In series with a load.

What will happen to the ammeter reading if the resistance is increased?
The current decreases due to I=V/R. The ammeter reading will decrease as R is increased.
What happen when a ammeter is placed in parallel with the circuit?
If an ammeter is placed in parallel with a a load on a circuit, the circuit can short out as the ammeter takes the place of the load, flowing freely through the meter. Never measure across a resister or other electronic load with an ammeter. Remember, ammeters are used in series while voltmeters are used in parallel.
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.
What happens when an ammeter is connected in parallel with a circuit?
SMOKE!!! Yiii-haaaa! An ammeter is always as low a resistance as possible. That way, the current that you measure in a circuit using the meter will be the same as if the meter were not there. So putting an ammeter in parallel with a circuit means that you just short circuited the circuit you were intending to measure. Poof! There goes your ammeter!An ammeter has a very low internal resistance. So, if it is connected in parallel with a load, it will short-out that load. The resulting high current flowing through the ammeter may severely damage the meter (and possible harm the user), although most are fitted with fuses to protect them.
What happens when Passive spinal movement under a load results in?
increased pressure on disks
