ammeter applied in series curict  and voltage is applied in parllel why

Ammeter is a device that measures the amount of current. Now, current is the charge flowing through a particular area of cross-section.
Hence, in order to measure the current flowing through a wire, or a resistor or any other component in the circuit, the ammeter has to be connected in series with that component.
If it is connected in parallel, then it would not give the actual reading of current gets divided into two branches.
 
 
Voltmeter is a device that measures voltage (or potential difference) across the terminal of a resistor or any other component of the circuit.
Hence, in order to measure the voltage across a resistor or any component, the voltmeter has to be connected in parallel as it would then measure the potential difference between the two ends of that component.
If it is connected in series then it would give the potential difference across the two points where it is connected and not the actual component.

The flow of electrons is opposite to the direction of the flow of current as electron is negatively charged . Then why current is defined as the flow of electrons through the conductor though current travels from positive to negative terminal.
