Question

PHYSICS 2525 Exam 3 Date: Name: 5. (12 pt.) An AC generator supplies a voltage V- Va sin(ax), with The generator is connected in series with a 50.00 ? resistor. What is the rms voltage supplied by the generator? a. b. What is the rms current supplied by the generator? c. What is the average power delivered? d. What is the maximum power? 6. (20 pt.) AC generator supplies an RMS voltage of ms-100 V, and frequency, f- 60.0 Hz (angular frequency o 377 rad/s.) The generator is connected in series with a 15.0 ? resistor, a 50.0 mH inductor, and a 679 ?F capacitor. a. (4pt.) What is the impedance, Z

Explanation / Answer

5. (A) V_rms = v_max / sqrt(2) = 100 / sqrt(2)

v_rms = 70.7 Volt

(B) Irms = V_rms / R = 70.7 / 50 = 1.41 A  

(C) P_avg = Irms^2 R = 100 W  

(D) P_max = Imax^2 R = 2 (Pavg) = 200 W
