Voltmeter

What is it?
A voltmeter measures voltage — the strength of the “push” of electricity in a circuit. It shows how much energy a battery or generator can provide.

Where do I use it?

• Wind Power Generator – Measure how wind speed changes electrical output.
• Geosynchronous Satellite – Test battery levels before spinning your model.

Why is it important?
Voltage testing helps engineers and electricians keep systems safe and reliable. In STEM kits, it teaches how electrical energy changes over time and how power affects motion or light.

STEM Skill Focus

• Collect accurate electrical data.
• Understand energy transfer in systems.
