All Three Circuits Below Have R = 100 Ω, C

question 54

Multiple Choice

All three circuits below have R = 100 Ω, C = 1.0 mF, and emf ε = (5.0 V) sin (377 t) . The inductors in (B) and (C) are placed sufficiently far apart so that they do not alter one another's inductance. Such inductors add combine like resistors. Which statement regarding the angular resonance frequencies ωA, ωB, and ωC is correct? ​ ​

• A)ωC > ωA = ωB
• B)ωC < ωA = ωB
• C)ωA = ωB = ωC
• D)ωB < ωA = ωC
• E)ωB > ωA = ωC
