- 3.6: Sinusoidal Steady State and the Series RLC Circuit
- Phasors may be used to analyze the behavior of electrical and mechanical systems that have reached a kind of equilibrium called sinusoidal steady state. In the sinusoidal steady state, every voltage and current (or force and velocity) in a system is sinusoidal with angular frequency ω . However, the amplitudes and phases of these sinusoidal voltages and currents are all different.
