Given information
Given a source emf and asked to describe how the frequency of the source emf affects the impedance of an LRC circuit far from resonance with small R value.
Step-by-step explanation
Step 1.
The impedance of an LRC circuit with a small R very far from resonance depends on whether the source frequency is much higher or much lower than the resonance frequency.
dominates at high frequencies and dominates at low frequencies.
