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 / 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

Answer / t e rao
sai phani kumar answer is correct.
Current flow will be same in all the elements. so
calculation should be done with reference to current.
Voltage across resistor Vr= 40+j0
Voltage across inductor Vl= 0+J70 (Since volage leads the
current by 90 degress)
Voltage across capacitor Vc= 0-J100 (since voltage lags the
current by 90 degress)
Total voltage = Vector sum of Vr + Vl + Vc
= 40+j0 + 0+J70 + 0-J100
= 40 - j30
Magnitude of voltage = 40-j30 = 50Voltage (with 38.6deg lag
to the current)
