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.
Average Voltages of Pulsating DC Voltages
In this learning activity, learners will learn to calculate the average voltage produced by half-wave and full-wave rectifiers.
Opens and Shorts in a Parallel Circuit
Learners examine the changes in current and voltage values in a parallel circuit when open and short conditions develop. Ohm's Law calculations are shown, and a brief quiz completes the activity.
Analog Ammeter Operation
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
