R, L & C Impedance in AC Circuits | Phasor Domain, Reactance & Admittance | GATE ECE

What happens to a resistor, inductor, and capacitor when we move from the time domain to the phasor domain? In this video, we learn the impedance of R, L, and C in AC circuits and build the foundation needed for AC circuit analysis and GATE ECE problems. We cover: • Impedance and the phasor form of Ohm’s law • Resistor impedance • Inductor impedance • Capacitor impedance • Voltage-current phase relationships • Current leading voltage in capacitors • Inductive and capacitive reactance • Positive and negative reactance • How to identify inductive, capacitive, and purely resistive impedance • Admittance • Effect of frequency on inductors and capacitors • Series RLC impedance • Series resonance condition • Parallel resonance condition This video is designed for *GATE ECE 2027 beginners* and is part of the AC circuit analysis series. #GATEECE #NetworkTheory #ACCircuits
