WebWhen resistors and capacitors are mixed together in parallel circuits (just as in series circuits), the total impedance will have a phase angle somewhere between 0° and -90°. The circuit current will have a phase angle somewhere between 0° and +90°. 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). WebPower delivery in an AC system depends on the phase angle between voltage and current. The phase angle also depends on the impedance of the circuit, which induces a phase … star wars rocky horror
