Alternating CurrentHard
Question
A circuit is set up by connecting L = 100 mH, C = 5 πF and R =100 Ω in series. An alternating emf of (150√2) volt, 500/π Hz is applied across this series combination. Which of the following is correct
Options
A.the impedance of the circuit is 141.4 Ω
B.the average power dissipated across resistance 225 W
C.the average power dissipated across resistance 225 W
D.the average power dissipated across capacitor is zero.
Solution
Z = 
= 100√2
Irms =
PR = Irms2 R
PL = 0
PC = 0
= 100√2Irms =
PR = Irms2 R
PL = 0
PC = 0
