An ac generator with emf amplitude m 220 V and operating at frequency 400 Hz causes
Chapter 31, Problem 44(choose chapter or problem)
An ac generator with emf amplitude m 220 V and operating at frequency 400 Hz causes oscillations in a series RLC circuit having R 220 , L 150 mH, and C 24.0 mF. Find (a) the capacitive reactance XC, (b) the impedance Z, and (c) the current amplitude I. A second capacitor of the same capacitance is then connected in series with the other components. Determine whether the values of (d) XC, (e) Z, and (f) I increase, decrease, or remain the same. 4
