Unformatted text preview: lakha (ml29327) HW#7 Jaafari (1444) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points The alternating voltage of a generator is rep- resented by the equation E = E sin t , where E is in volts, E = 313 V, = 295 rad / s, and t is in seconds. Find the frequency of the electric potential E . Correct answer: 46 . 9507 Hz. Explanation: Let : E max = E = 313 V , and = 295 rad / s . = 2 f f = 2 = 295 rad / s 2 = 46 . 9507 Hz . 002 (part 2 of 2) 10.0 points Find the voltage output of the source. Correct answer: 221 . 324 V. Explanation: The rms voltage is E rms = E max 2 = 313 V 2 = 221 . 324 V . 003 (part 1 of 2) 10.0 points The alternating potential difference of a gen- erator is represented by the equation E = (312 V) sin(355 rad / s) t , where E is in volts and t is in seconds....
