Lesson 3: RLC circuits & resonance

Example of a simple “tank” (LC) circuit • What is the total impedance of the circuits? • So the tank circuit behaves as an open circuit at resonance • In a very similar way one can show that a series LC circuit behaves as a short circuit when driven on resonance i e , − = − =i L −L = ⇒Z =∞ C i Z 1 iL ( ω ω) 0 ω ω Z =0
