Unformatted text preview: Chapter 24 Equations AC Circuit Equations Angular Velocity Equations: There are several equations for angular velocity . Often, you need to switch one form of this quantity out for another in the equations below. appears a lot and most often gets written as 2 f , where f is frequency. On rare occasions, it gets written as the tangential velocity v divided by the radius r . You probably won't see that one. Voltage Equation: the voltage changes over time in an AC circuit. Here, v is the voltage at a given time, v is the maximum voltage, is the angular velocity, and t is time. Current Equation: like voltage, current changes over time in an AC circuit. Here, i is the current at a given time, i is the maximum current, is the angular velocity, and t is time. RMS Equations: in an AC circuit, both the voltage and the current have maximum and average values. The maximum values are denoted as v and i . The average values are denoted as v rms and i rms . These maximum and average values are related by a simple ratio involving the square root of two....
