In this animated object, learners examine the operation of a temperature alarm circuit that uses a thermistor in a Wheatstone Bridge.

Learners use two calculations to prepare a graphical solution to the biasing of bipolar junction transistors and junction field effect transistors. This method eliminates the problem of having to re-calculate the operational Q point when dealing with hard saturation.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.

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 by each resistor.

In this learning activity you'll discover how to calculate the best priced items and improve your financial literacy.

Students use the pyramid method to solve percent problems. The pyramid grid provides a visual way to set up the equation.

Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.

Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.

Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.
