You decide to use a toaster to toast a slice of bread using the wall outlet of your home. Knowing that the voltage supply of your home is alternating given by the function V = 120 sin sin (2 πft), where ƒ = 120 [Hz] and t is time in seconds, answer the following questions a) If the toaster oven uses nichrome wire that measures a total length of 0.25 [m] with a thickness of 0.5 [mm] (diameter of wire), what is the resistance of the wire when heats up to 100.0 [°C] from room temperature of 20.0 [°C]? P value is 100*10^-8 and alphas value is 0.4*10^-3 b) Knowing the resistance value of the wire from part a) and using Ohms Law, write the alternating current equation. c) What is the rms value for current and voltage for our toaster oven circuit? d) How much average electrical energy [J] does your toaster oven use if you toast your bread for 1 minute? (Hint: What are the units of power and how is it related to energy?)
