In an RLC series circuit, if the total impedance is 50 ohms and the resistance is 30 ohms, what is the reactance? (2020)

Step 1: Identify the given values. The total impedance (Z) is 50 ohms and the resistance (R) is 30 ohms.
Step 2: Write down the formula for impedance in an RLC circuit: Z = √(R² + X²), where X is the reactance.
Step 3: Rearrange the formula to solve for reactance (X): X = √(Z² - R²).
Step 4: Substitute the known values into the formula: X = √(50² - 30²).
Step 5: Calculate 50², which is 2500.
Step 6: Calculate 30², which is 900.
Step 7: Subtract 900 from 2500: 2500 - 900 = 1600.
Step 8: Take the square root of 1600: √1600 = 40.
Step 9: Conclude that the reactance (X) is 40 ohms.
