A resistor,inductor and capacitor are connected in series
respectively.Voltage across resistor is 40v,across inductor is
70v,across capacitor is 100v.Then what is the total voltage
applied across the elements?

Answer Posted / sai phani kumar

Voltage across resistor Vr= 40
Voltage across inductor Vl= J70 (Since current lags volage
by 90 degress)
Voltage across capacitor Vc= -J100 (since current leads
voltage by 90 degress)

Total voltage = Vector sum of Vr + Vl + Vc
= 40 + J70 -j100
= 40 - j30
Magnitude of voltage = 50

Is This Answer Correct ?    8 Yes 1 No
