An ammeter can cause a short circuit if it is connected in parallel instead of in series with the circuit being measured. This can create a low resistance path for the current to flow, bypassing the intended circuit and causing a short circuit.
Connecting an ammeter directly across a voltage source can cause a short circuit, damaging the ammeter and potentially causing overheating or even a fire hazard. This is because an ammeter has a low resistance, which could cause a very high current to flow through the circuit, overwhelming the device and damaging it. It is important to always connect an ammeter in series with the circuit to measure current accurately and safely.
An ammeter reads the current that is flowing through a branch of a circuit. If there is a break within that same branch of the circuit, current will not be able to flow through that branch of the circuit as it forms an incomplete loop, so the ammeter will read 0 A of current. If there is a break in a circuit in a branch that is not connected to the ammeter however, the ammeter will give a higher reading of the current. This is assuming that the break in the other branch does not short out the branch with the ammeter attached, and that the circuit can still form a complete loop without that branch.
Zero. No current is flowing in an open circuit. The ammeter will display an amount of 0 amps because there is no longer any current once the circuit has been broken. An ammeter measures current.
The decrease of light intensity on an LDR will cause the resistance of the LDR to increase, which will result in a decrease in current flow through the circuit. As a result, the ammeter reading will decrease.
An Ammeter provides a visual display of the magnitude of the current flowing through it. Ideally, the ammeter does nothing "in the circuit". You don't want your test equipment to change anything going on in the circuit you're measuring.

How do you connect an ammeter to a circuit?
In series with the circuit and never in parallel. The reason being that it will cause the circuit total resistance to drop which will make the circuit draw excessive current. That's a short circuit actually.
The voltage remains the same across the circuit as it is a parallel connection. So, the current across the upper half of the circuit where the ammeter is connected is calculated as I = V/R = 12.04 (total voltage)/12 (Resistance R1) = 1 A. Hence, the ammeter will read 1 A.
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.

Connecting an ammeter in parallel with a circuit element is hazardous. Because of its negligible resistance, it is equivalent to applying a short circuit across that element, and the resulting current through the ammeter may severely damage the instrument if it is not fused.
An ammeter is always connected in series in the 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.
An ammeter measured how many amperes of current are flowing in an electrical circuit.
Because the ammeter connected in parallel will act as a short circuit.
connect ammeter in series with load.
