What is the effect of increasing the frequency on the total impedance of an RLC circuit? (2020)

Step 1: Understand that an RLC circuit has three components: a resistor (R), an inductor (L), and a capacitor (C).
Step 2: Know that the total impedance (Z) of the circuit depends on the resistance (R), inductive reactance (XL), and capacitive reactance (XC).
Step 3: Recognize that inductive reactance (XL) increases with frequency. The formula is XL = 2πfL, where f is the frequency.
Step 4: Understand that capacitive reactance (XC) decreases with frequency. The formula is XC = 1/(2πfC).
Step 5: As frequency increases, XL goes up and XC goes down.
Step 6: Determine the total impedance (Z) using the formula Z = R + j(XL - XC), where j is the imaginary unit.
Step 7: Analyze the relationship: If XL becomes much larger than XC, Z increases. If XC is larger than XL, Z decreases.
Step 8: Conclude that the effect of increasing frequency on total impedance depends on the values of R, XL, and XC.
