1. 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
