why is an ammeter connected in series?

Expert Answer:

In series connection, the same current flows through all the components. Ammeter aims at measuring the current flowing through the circuit and hence, it is connected in series: so that the same current that is there in the circuit flows through it and gets measured.
 
Ammeter has a low resistance, because we do not want to change the current that is flowing through the circuit. In case of a high resistance in ammeter, it will cause additional voltage drop across it, changing the current that is flowing through the circuit. To minimize the voltage drop and hence the current change, we use a very small resistance in ammeter.
