In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.
Transistor Fundamentals: E-MOSFETs, the Ohmic Region
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 review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
In this animated object, learners examine formulas for displacement and velocity ratios. They also view examples and calculate velocity and the velocity ratio.
Op Amp Fundamentals: The Transresistance Amplifier
The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
In this interactive object, learners examine the operation of an inverting operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
In this animated and interactive object, learners examine the definitions and formulas for radius, diameter, circumference, and area. Students also solve practice problems involving the circumference and area of a circle.
