Questions & Step-by-Step Solutions
In a series RLC circuit, if the resistance is increased, what happens to the bandwidth of the resonance peak?
Step 1: Understand what a series RLC circuit is. It consists of a resistor (R), inductor (L), and capacitor (C) connected in series.
Step 2: Learn about resonance in the circuit. Resonance occurs at a specific frequency where the circuit can oscillate with maximum amplitude.
Step 3: Know what bandwidth means. Bandwidth is the range of frequencies around the resonance frequency where the circuit can still operate effectively.
Step 4: Recognize the role of resistance in the circuit. Higher resistance means more energy is lost as heat, which affects how sharply the circuit can resonate.
Step 5: Realize that increasing resistance makes the resonance peak narrower. This is because the circuit can no longer sustain oscillations over a wide range of frequencies.
Step 6: Conclude that as resistance increases, the bandwidth of the resonance peak decreases.
