Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
Instantaneous Voltage Calculations of a Discharging RC Circuit (Using a TI-35X or a TI-36X Calculator)
In this animated object, learners view the keystrokes on a TI-35X/36X calculator that are required to solve for the instantaneous voltage of a discharging RC circuit.
Discharging Time Constants of an RC Circuit (Screencast)
In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.
Series Circuit Analysis Practice Problems: Circuit #9
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.
Bloodborne Pathogens: Risks of Exposure and Means of Transmission
In this interactive object, learners read about the occupations that are most at risk for bloodborne pathogen exposure. They also read about the most common pathogens and how they are transmitted. This learning object is based on information from the U.S. Occupational Safety and Health Administration.
In this learning activity you'll review how every protein molecule of an organism is synthesized by that organism in a prescribed process. This activity helps students understand the fundamental life process of making protein.
Grouped Numerical Frequency Distributions: An Overview -- First in a Series
In this interactive object, students read about organizing data in a tabular form. A brief quiz completes the activity. This is the first in a series of six learning objects.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
