In principle, it is possible to cook a hot dog by connecting it directly a to 120 V household electricity. For this problem, assume the hot dog is 22 cm long, 4 cm in diameter, has a mass of 70 g and a resistance of 300 Ω. The specific heat of a hot dog is about 3400 J/kg•K.

What is the electric field inside the hot dog?

Final answer:

The electric field inside the hot dog when subjected to a 120 V household current is 545.45 V/m, calculated by dividing the voltage by the length of the hot dog.

Step-by-step explanation:

The question is about calculating the electric field inside the hot dog when it is connected to a 120 V household electricity. According to Ohm's Law, the electric field (E) inside a material is given by the voltage (V) divided by the length (L) of the material:

E = V / L

Here, the length (L) of the hot dog is 22 cm, which we need to convert into meters by dividing by 100 to get:

L = 22 cm / 100 = 0.22 m

Given the voltage (V) is 120 V, we can now calculate the electric field (E) as:

E = 120 V / 0.22 m

E = 545.45 V/m

Therefore, the electric field inside the hot dog is 545.45 V/m.
