An AC generator with an rms voltage of 12.0 V is connected in series with a 0.60-H inductor. The frequency of the source voltage is 50.0 Hz. (a) What is the inductive reactance of the circuit? (b) What is the rms current in the circuit?(c) What is the maximum value of the current in the circuit?(d) Write an expression for the potential difference across the inductor as a function of time.

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 × 10-6 ω·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 ¢ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to it’s resistivity when at operating temperature? explain.
