Hint:In order to solve this question, we should know that here ammeter is asked in the context of instruments used in electrical experiments and here we will discuss about ammeter and the meaning of $200m$ on multimeter.

Complete answer:
There are many important instruments that are used while doing any electrical experiment related to electricity and magnetism in the laboratory but among all the three main and most useful in almost all experiments are the ammeter, voltmeter, and multimeter.

An ammeter is an electrical instrument that is used to determine the current flowing in any part of the circuit and ammeter is always connected in series in the circuit while a voltmeter is used to determine the potential difference between any two points in the circuit and voltmeter is connected in parallel in the circuit.

A multimeter is used to determine multiple values like current, voltage, and resistance and for the specific purposes its used and when we want to measure the current through a multimeter and it gives a reading in the units of ‘m’ as we have been given as $200m$ on multimeter means the value of current in the circuit is of $200$ in magnitude and in the units of a milliampere. milliampere is the smaller unit of current. Similarly, if the multimeter reads $200mV$ then mV is the unit of voltage called millivolts.

Hence, $200m$ on the multimeter means the value of current in the circuit is $200$ milliamperes.

Note: A milliampere is the smaller unit of current and the SI unit of current is amperes denoted by A. the basic conversion relation between milliampere and ampere is related as $1mA = {10^{ - 3}}A$.
