Learners analyze a base-biased npn transistor circuit. A "help" screen is available.

Learners examine the information on a title block and answer questions about that information in an interactive quiz.

Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.

In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.

Learners read the definitions of working capital, current ratio, quick ratio, return on equity, accounts receivable turnover, and inventory turnover.

Learners consider why an impedance matching transformer is needed to connect an antenna to a television.

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.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

This math review game is focusing on ratio and percent problems. This is to help prepare for the 6th grade math EOG.

This game will review primary, secondary, warm and cool color schemes.

ratios, equivalent ratios, and ratios in simplest form
