Wires are necessary to make a complete electrical circuit.
For example they are needed to bring the electricity to the load (like a bulb) from one side of the source (like a battery "+" terminal) and then take it back to the other side of the source (the battery's "-" terminal).
Another take
A wire allows the electricity (called Current) a path to travel through it, based on the difference in potential (aka Voltage) between the components (for example, Resistors).
Key note: the wires must be connected to make the path a complete LOOP. i.e. if there is no connection back to where you started from, there is no flow.
To describe it more completely:
Current flows through components as well. So, say if the resistor is a light bulb and the filament blows, then the loop path is not complete anymore.
After you get this idea search for the term "Ohm's law" to get a handle on electric circuits. (Kirchoff's voltage law and Kirchoff's current law are the other big ideas)
Oh, and in case you didn't know: the battery is the thing making "the difference in potential" I talked about. Additionally: Resistors aren't the only components: the other 2 are called Capacitors and Inductors. In circuit analysis they function as a slightly more complex form of Resistance that's called Impedance.

Why electric current across a wire drops?
Electric current does not drop. Electric voltage, however, drops across a wire because the wire has non-zero resistance. (Do not confuse electric current with electric voltage - they are not the same.)The reason current does not drop is that, in a series circuit, according to Kirchoff's current law, the current at every point in a series circuit is the same.

What is the relationship between electric potential and a wire in an electrical circuit?
The electric potential in a wire in an electrical circuit is the amount of electric potential energy per unit charge. As the wire carries current, the electric potential decreases along the wire due to the resistance of the wire. This relationship is described by Ohm's Law, which states that the electric potential difference across a wire is directly proportional to the current flowing through it and inversely proportional to the resistance of the wire.
What is the function of a neutral wire in an electrical circuit?
The function of a neutral wire in an electrical circuit is to provide a return path for the current to flow back to the power source, completing the circuit and ensuring a balanced flow of electricity.
