All three circuits shown below have R = 100 Ω,L = 0.1 H and emf ε = (5.0 V)sin (377 t).Which statement regarding the angular resonance frequencies ω_A,ω_B and ω_C is correct? A)ω_C > ω_A = ω_B B)ω_C < ω_A = ω_B C)ω_A = ω_B = ω_C D)ω_B < ω_A = ω_C E)ω_B > ω_A = ω_C

Quizplus · Accepted Answer

The resonant frequency of an RLC circuit is given by: ω0 = 1/√(LC) For all three circuits, R = 100 Ω and L = 0.1 H are the same. Therefore, the resonant frequency ω0 is also the same for all three circuits. It does not depend on the value of the emf ε. Hence, the answer is C: ω_A = ω_B = ω_C.
