An Introduction to the Digital Multimeter
By Patrick Hoppe
In this learning activity you'll explore the functions and proper operation of a digital multimeter.
Series-Parallel Practice Problems Circuit 4
In this interactive object, learners work 12 problems dealing with dc circuit analysis.
Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.
Sine Wave Fundamentals
Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.
Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.
Parallel RL Circuit Vector and Circuit Analyzer
By James Bourassa, John Rosz
Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
Op Amp Fundamentals: The Non-Inverting Amplifier
Students are introduced to the non-inverting amplifier configuration. The formulas for closed loop gain and bandwidth are shown, and an example is given.
The DC Motor
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
Voltage Divider Rule Practice Problems
Learners review the VDR and work six problems. Immediate feedback is given.
