This technique is a remnant of ... WebSince XL < XC, the phase angle for the current in the circuit is negative. If we increase the frequency above the resonant frequency, XL (= ω L) increases and XC (= 1/ω C) decreases. At 503 kHz, XL is about 9.48 kΩ, and XC is about 1.44 kΩ. The impedance of both together is about 9.37 kΩ (√ ( XL2 - XC2) ≈ 9.37 kΩ). population forecasting model
