extension cord (t) = v2 · 10 cos(120rt) to a load. You have a choice of extension chords with 16 to deliver a current AWG (light duty) or 12 AWG (heavy duty) vire. -- 100 ft What is the ratio of the volume of copper in the 12-gauge cord to the volume of copper in the 16- gauge cord? Suppose the 16-gauge cord costs $30 and the 12-gauge cord costs $60. Electricity costs $0.10 per kilowatt-hour (kWh). You will use the extension cord to deliver current continuously (24/7) for y vears. Solve for the functions c12(y), C16 (y) that give the total cost of using the 12- and 16-gauge extension cords for y years (including the purchase price). For what values of y is the 12-gauge cord more economical? Note that 1 year is 365.25 days.

You have measured both of the series and shunt field windings and found that each has over 10 mega ohm to ground. Your ohm meter, however indicates a resistance of 1.5 ohms across terminals S1 and S2. The ohmmeter indicates a resistance of 225 ohms between terminal F1 and F2. Are these readings normal for this type of machine, or is there likely a problem?
