Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Students review the Current Divider Rule (CDR) and work practice problems.

In this learning activity you'll build a resistor's color code based on the bands.

Learners examine three formulas than can be used to find dc power. Examples are given.

Students read how the transfer function for a RC low pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

The technique for designing a MOD 10 counter is introduced. Asynchronous inputs of a JK flip-flop are used to clear the counter.

Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.
