(h) What is the resonant angular frequency ωres of an RCL circuit with inductance L = 7.4 mH and capacitance C?
(h) What is the resonant angular frequency ωres of an RCL circuit with inductance L = 7.4 mH and capacitance C = 157 µF?
At resonance, Xl + Xc = 0 thus
ωL + (-1/ωC) = 0
ωL = 1/ωC
ω² = 1 / LC
ω = √( 1 / LC )
ω = √ [ 1 / ( .0074 H )( .000157 F ) ]
ω = 927.75 rad/sec
