    We all know that a battery establishes an electric field in the wires.

    When a conducting wire is connected to a positively charged body, the nearest free electrons of the wire will "jump" on the body (due to the force of the charged body acting on them) and thus "uncover" the positive charge of several nuclei in that part of the wire. These positively charged nuclei will attract electrons situated further along the wire, making them to move and "uncover" another set of nuclei. This process goes on and on until the end of the wire is reached. If this end is connected to a negatively charged body, the process is even more intensified.

    This is how an electric field is established.
    MY doubt is
    Does the resistance connected in the circuit has any effect on the electric field? i.e does it alter the electric field in the wires as a result changing the effective attraction towards the electrons in the wire??

    Many wires are considered perfect conductors and are used with circuit elements that are not. In a perfect conductior there is no static electirc field, almost by definition.
