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.
Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.
Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.
Digital Multimeter/Ohmmeter Measurement Connections
In this animated activity, learners follow a step-by-step approach for connecting a digital multimeter to measure resistance. A brief quiz completes the activity.
In this animated object, learners examine the operation of a thermal flowmeter used in process control applications. A brief quiz completes the activity.
Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.
