    Answer:

    the electric field strength inside the resistor is 2.57 V/m

    Explanation:

    Given;

    current flowing through the wire, I = 1.10 A

    resistance of the wire, R = 7.00 Ω

    length of the wire, L = 3.00 m

    The emf created inside the resistor is calculated as;

    V = IR

    V = 1.10 x 7

    V = 7.7 V

    The electric field strength inside the resistor is calculated as;

    E = V/L

    E = 7.7 / 3

    E = 2.57 V/m

    Therefore, the electric field strength inside the resistor is 2.57 V/m
