Support for Java Applets, including Physlets, has been discontinued by browsers and Oracle. Thus, traditional Java-based Physlets are no longer supported on this website. Please note Open Source Physics (OSP) Java programs continue to run on computers with Java if users download the jar file.

The OSP team is busy updating and developing simulations using HTML5 + JavaScript.
These simulations run on almost all platforms including tablets and cellphones. Explore the Third Edition of Physlets Physics or search OSP for JavaScript to find these simulations.

Chapter 31: AC Circuits

Alternating Current (AC) circuits are circuits where the current and the voltage vary sinusoidally in time (in comparison with DC circuits where the voltage and current are constant). AC is the type of current you get from wall outlets; the current switches direction 60 times a second (60 Hz current). With AC, we begin the study of circuits with non-linear circuit elements such as capacitors, inductors and transformers, which are the back-bone of analog and power electronics.
