📏 Measuring Potential Difference
Instrument: Voltmeter
How to connect: In PARALLEL — across the component you're measuring.
Why parallel? Voltage is the energy difference between two points. The voltmeter compares the energy level of charges entering and leaving a component — it must touch both sides simultaneously.
Circuit symbol: Circle with V inside
