Question

Common household electric current is called alternating current because the current alternates direction within the wires The voltage V in a typical 115 volt outlet can be expressed by the function V t 163 sin ot where is the angular speed in radians per second of the rotating generator at the electrical plant and t is the time measured in seconds It is essential for electric generators to rotate at precisely 60 cycles per sec Complete parts a and b a How many times does the current oscillate in 0 40 sec 24 time s b What are the maximum and minimum voltages in this outlet Is the voltage always equal to 115 volts The maximum voltage is 163 V and the minimum voltage is 163 V Is the voltage always equal to 115 volts OYes O No
