Answer #1

Ammeter :
   Ammeter is a measuring instrument which measures the current through a circuit. It has a low internal resistance. So, in order to measure the current through the circuit, we need to connect the ammeter in the series so that the current to be measured flows directly through the ammeter. In the circuit diagram it is shown as
   

Voltmeter :
    Voltmeter is a measuring instrument which measures the voltage accross an element of a circuit. It has a high internal resistance. So, in order to measure the voltage accross an element of a circuit, we need to connect the voltmeter in the parallel. In the circuit diagram, it is given as
