Ammeter is connected in series with equipment and it can also be said that is connected through equipment not across as across means it is connected in parallel.

Across the circuit means parallel, so there is not confusing about question.
Current measuring in a circuit ammeter must connected in series.

Ammeter should be connected in series to measure current flowing through it.
Reasons for connecting in series are.
1. Because current will be same in series but in case of parallel (shunt) current will divide.
2. Its resistance will be low (negligible) so we will connect in series. If we connect in parallel, it is nothing but short circuiting both phase & neutral in case of AC. And in case of DC short circuiting positive and negative.

An ammeter is always conncted in series with the line to read out the current flowing through the line.

Ammeter is a current measurement device in these meter has coil is very heavy compare to volt meter so in serially connect to the load.

An ammeter is always connected in series to make the circuit condition same. Or due to low resistance.

An ammeter should always connected in series because:
The purpose of the ammeter is to measure the current through the circuit. Since the ammeter is a low impedance device, connecting it in parallel with the circuit would cause a short circuit, damaging the ammeter and/or the circuit.
1. It should be connected in series, so that maximum current can pass through it, for accurate measurement of current.
2. Its resistance is very low, if it is connected in parallel in a circuit, it will by the current, and current can not be measured accurately.
If you do not connect the ammeter in series you will shunt the load, basically excluding the resistive element of the circuit.

Ammeter act as short circuit then only it connects in series.

I think this question is so confusing. Current path doesn't indicate any series path.

The question asked is "An ammeter is connected across the current path".
In this question the word across means pararell.
So that we not connect ammeter with pararell and ammeter connected in series.
