Learners read an analogy comparing an electrical transformer to mechanical gears.
Schematic Diagram Symbols
By Terry Bartelt
In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.
Series Circuit Analysis Practice Problems Part 1
By Patrick Hoppe
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.
Analog Position Control
In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.
Finding the Common Connection of an SPDT Switch
In this animated object, learners examine the procedure used to determine the types of terminals on a single-pole, double-throw switch.
Financial Statement Analysis
By Lynette Teal
Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.
An Impedance Matching Application
Learners consider why an impedance matching transformer is needed to connect an antenna to a television.
The Reflected Load in a Transformer
Learners examine how the load resistance connected to the secondary coil of a transformer affects the primary current. A brief quiz completes the activity.
Learners examine the impedance matching capability of a transformer and how to select the proper turns ratio to achieve this function. A brief quiz completes the activity.
Transformer Action Demonstration
Learners view animations and video clips showing how power is transmitted from one energized coil to another.
Ratio Review Game
This math review game is focusing on ratio and percent problems. This is to help prepare for the 6th grade math EOG.
