The Mathematical Expression of an AC Sine Wave As a Function of Time: Practice Problems
Students view the mathematical expression of a sinusoidal waveform with respect to time (t) and solve five problems. The answers are provided so students may check their work.
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.
Learners review Ohm's Law and 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.
Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.
