A voltage of peak value 283 V varying frequency is applied to a series L-C-R combination in which R = 3W; L = 25 mH and C = 400 mF. Then, the frequency (in Hz) of the source at which maximum power is dissipated in the above, is
  • a)
    51.5
  • b)
     50.7
  • c)
    51.1 
  • d)
    50.3
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
A voltage of peak value 283 V varying frequency is applied to a series...
Here, V0​=283V,R=3Ω,L=25×10−3H
C=400μF=4×10−4F
Maximum power is dissipated at resonance, for which 
 
ν=1/[2π√(LC)]​​= (1×7​)/[2×22(25×10−3×4×10−4)]
=(7×103​)/(44√10​)
=50.3Hz
