In this learning activity you'll review how a short affects current flow and voltage in a series circuit.
Learners observe current flow throughout the series portion and branches of a parallel circuit. This animated activity includes calculations and a short quiz.
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
In this interactive and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.
This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.
In this learning activity you'll explain how voltage and resistance in a series circuit affect current flow.
In this learning activity you'll review how an open in a series circuit affects current.
Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.
Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.
Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.
In this interactive object, learners vary the value of the resistance to see how it affects current. Example problems are included.
Learners view an animation showing the operation of a Vortex flowmeter that is used to measure flow in a process control system.
Learners follow step-by-step instructions for creating a current-state map to identify how materials and information flow.
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.
In this learning activity you'll understand what flow charts are and how they're used to create computer programs.
Students determine what happens to current flow in a series circuit when the resistance is changed. A brief quiz concludes the activity.
