In an RLC circuit, if the resistance is increased, what happens to the quality factor (Q)? (2021)
Step 1: Understand what an RLC circuit is. It consists of a resistor (R), inductor (L), and capacitor (C).
Step 2: Learn about the quality factor (Q). It measures how underdamped an oscillator or resonator is, and it indicates the sharpness of the resonance peak.
Step 3: Know the relationship between resistance and quality factor. The formula for Q is Q = (1/R) * sqrt(L/C), where R is resistance, L is inductance, and C is capacitance.
Step 4: Observe that in the formula, Q is inversely proportional to R. This means that as R increases, Q decreases.
Step 5: Conclude that if the resistance in the RLC circuit is increased, the quality factor Q will decrease.
