An RLC Series Circuit Is Driven by a Sinusoidal Emf $\omega$

question 14

Multiple Choice

An RLC series circuit is driven by a sinusoidal emf with angular frequency $\omega$ _d. If $\omega$ _d is increased without changing the amplitude of the emf the current amplitude increases. If the L is inductance, C is the capacitance, and R is the resistance, this means that:

• A) \( \omega \)_dL > 1/ \( \omega \)_dC
• B) \( \omega \)_dL < 1/ \( \omega \)_dC
• C) \( \omega \)_dL = 1/ \( \omega \)_dC
• D) \( \omega \)_dL > R
• E) \( \omega \)_dL < R
