The electricity in a U.S. house is called alternating current (AC) because the voltage and current vary sinusoidally with time. Assume that the frequency is 60 cycles/second and that the voltage range is [-170, +170] volts. Assume voltage is at its maximum when time a.) b.) t = 0.005556 second. Write a sinusoidal function V(t) to model that voltage, where It is in seconds. Use your function to determine the voltage at t = 0.008 sec.

A sinusoidal current wave has an instantaneous value of -20 A at t = 0 and is increasing negatively. If the peak value is 50 A, solve for the instantaneous value of the current when t = 3 milliseconds and at t = 40 milliseconds. At what time will the instantaneous value of the current be -30 A for the 4th time.

QUESTION 11 An inductor is connected in parallel with a 6540 resistor and a function generator. The applied voltage is 42V RMS and the total current is 67mA RMS. Find the magnitude of the current through the inductor. Enter your answer in the space provided. Round your answer to one decimal place. Your answer should be in mA but do not enter the unit.
