Answer 1

Here. Vo = 240 V R = 2oo4, x = 7oor reactance of capacitor V = 56OV voltage amplitude across the capacitor current amplitude across the capacitor Now de = 2008 A the Now, because circuit is in series soo. current amplitude through circuit = 1 = 0. 8A = le - z = b = 200 - 300 12 z = 300r Parte let reactance of inductor is X = = √R?+ (x2-xcj2 - 300 = √2007+ (% - 70032 5) 2002 - 2002 = (X2 -700)? 7 X = 700 ± √ 300² - 2002 » XL = 700 I loors X = 924 0m, 4762
