In this animated activity, learners examine how ground fault circuit interrupters work and why they are an important safety feature.
In this interactive object, learners follow steps to find phase voltages in a partial three-phase power distribution circuit.
Students follow the steps that are required to select a transformer with the proper ratings. Voltage, frequency, current, and KVA are considered.
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Learners will identify ladder logic diagrams and the logic functions they perform.
The learner will examine the basic characteristics of the operational amplifier integrated circuit and solve for Vout.
The learner will describe the non-inverting op-amp configuration and calculate the circuit gain.
In this learning activity, we’ll explore the impact of electric shock on the human body.
The learner will calculate basic circuit resistance.
The learner will calculate input and output circuit resistance for the Inverting Op-Amp configuration.
The learner will be able to represent steady-state AC sinusoidal signals using phase vectors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
Explore the step-by-step procedures to rescue and care for electrical shock victims.
In this learning module, you'll explore what electrical grounding is, how it works, and some real-world applications.
Walk through the subscriber loop and learn how the signal travels from the central office to the subscriber.
