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
