A resistorand a capacitorare connected in seriesto a 50 Hz acsource . Thevoltage(rms ) acroossthe resistorand capacitorare 151 Vand 160.3 VrespectivelyCalculatethe rmsvoltageof thesource.Alsofindthe capactivereactanceadnimpedanceof thecircuit, if thecircuitis 0.755 A .

Answer»

SOLUTION :`V_R =151 V ,V_C=160.3V`
`V_(rms) = sqrt(V_(R)^(2) +V_(C)^(2))`
`= sqrt((151)^2 +(160 .3)^2)`
` V_(rms) = 220V `
Capacitivereactance :
`V_C =I X_C`
`X_C= (V_C)/(I ) = (160.3)/(0.755 )`
` X_C = 212.31 OMEGA `
impedance :
` Z=(V_(rms))/(I )= (220 )/(0.755)`
`Z = 291.39Omega `
