Students work six practice problems to determine the total capacitance of a series circuit. Immediate feedback is given.

In this animated object, learners examine the relationship between pressure and temperature in an air conditioning system.

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.

The schematic symbols of logic gates used in digital circuits are shown.

Students read the rules used in multiplying and dividing signed numbers. They view examples and work practice problems.

Students read how to organize their work when multiplying more than two signed numbers. A review and practice problems complete the activity.

Learners follow the steps for adding and subtracting signed numbers and complete practice exercises.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.

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.

This will help you with your multiplication facts. It has 3 times tables to 6 times tables. I plan to upgrade it later to at least 9 times tables.

Defining Negatives

You'll determine which of two options is the correct choice for rounding a given number to the nearest tenth, hundredth, or thousandth.
