Impedance in an AC circuit is a comprehensive concept that encompasses the effects of resistance, capacitance, and inductance. Each of these components plays a significant role in how the circuit responds to alternating current.

Resistance, which opposes current flow, simply dissipates energy in the form of heat, affecting the overall impedance. Capacitance stores energy in the electric field and can cause the current to lead the voltage, thus impacting the phase angle in the circuit. Inductance, on the other hand, stores energy in a magnetic field and can cause the current to lag behind the voltage, again influencing the phase relationship within the circuit.

When studied together, these three components create a complex interaction that determines the total impedance, which is represented as a complex number with both a real part (resistance) and an imaginary part (reactance from inductance and capacitance). Therefore, acknowledging resistance, capacitance, and inductance collectively is essential for understanding impedance in AC circuits.
