Definition
An electrical charge condition in which a material has fewer electrons than protons, giving it a net positive charge. A positively charged body will attract electrons from, or repel positive charges in, nearby materials.
Plain English
When something has lost some of its electrons, it ends up with more positive particles than negative ones. That imbalance is what we call a positive charge.
Context Anchor
Seen in aircraft electrical system discussions, battery polarity, wiring, and static electricity.
Derivation
From Latin positivus, meaning 'set in place' or 'definite.' Early researchers chose 'positive' and 'negative' as labels for the two opposing charge types before electrons were discovered. The label stuck, even though the positive terminal is actually the one missing electrons.
Why Pilots Care
Correct identification prevents miswiring batteries and helps anticipate static discharge during flight through clouds or precipitation.
Grounding Statement
If a surface loses electrons, it can be left with a positive electrical charge.
Intuition Check
Positive does not mean “good” or “safe” here. It means one side of an electrical condition, opposite of negative charge.
Example Sentence 1
The positive terminal of the aircraft battery is marked with a plus sign and connects to the starter circuit.
Example Sentence 2
Connecting the positive lead to the battery terminal completed the circuit and allowed current to flow to the avionics.
