Learners follow steps for reading a P&ID diagram of a closed-loop circuit.
Incremental Encoder Quadrature Modes
By Terry Bartelt
Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.
Pneumatic Directional Control Valves (Screencast)
In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.
Series RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Series Circuit Analysis Practice Problems: Circuit #10
By Patrick Hoppe
In this interactive object, learners solve for total resistance, total current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
A Summary of the Closing Process
By Lynette Teal
In this accounting learning object, students follow the steps involved in the closing process. Temporary accounts contain ending balances for a specified period and must be closed.
