In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

The ohmic region of the E-MOSFET is identified. Formulas are given to determine the proper operation in the ohmic region. An example of circuit analysis is also given.

Learners observe the waveforms in a circuit in which a triac controls the brightness of a lamp’s light. A brief quiz completes the activity.

In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

Students answer five questions concerning magnetism.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

In this animated object, learners observe the operation of a J thermocouple with a cold junction. A table is used to convert the voltage it produces to a corresponding temperature. A brief quiz completes the activity.
