A series LCR circuit is designed to resonate at an angular frequency ω0=105rads−1.{\omega}_{0} = {10}^{5}rad{s}^{- 1} . The circuit draws 16W16W power from 120V120V source at resonance. The value of resistance RR in the circuit is ________ Ω.Ω .

Correct answer

0

Step-by-step solution

At resonance

P=V2RP = \dfrac{{V}^{2}}{R}

R=V2P=(120)216R = \dfrac{{V}^{2}}{P} = \dfrac{{\left(120\right)}^{2}}{16}

=900Ω= 900Ω
