Phasor diagrams are used to analyze AC signals by representing them as rotating vectors.

AC signals are characterized by their amplitude, frequency and phase. Phasor diagrams are a graphical representation of AC signals that allow us to analyze their behavior over time. They are particularly useful for understanding the relationship between voltage and current in AC circuits.

In a phasor diagram, the AC signal is represented as a rotating vector. The length of the vector represents the amplitude of the signal and the angle it makes with a reference line represents the phase. By using trigonometry, we can calculate the real-time values of voltage and current at any point in the cycle.

Phasor diagrams are particularly useful for analyzing the behavior of AC circuits that contain capacitors and inductors. Capacitors and inductors introduce a phase shift between voltage and current, which can be represented using phasor diagrams.

Overall, phasor diagrams are a powerful tool for analyzing AC signals and understanding the behavior of AC circuits. They allow us to visualize complex waveforms and calculate real-time values of voltage and current, making them an essential tool for A-Level Physics students.
