Coulomb meter
Definition - A coulomb meter is a device used to measure the amount of electric charge an object has, usually in coulombs (C).
How does it measure?
A coulomb meter is a device used to measure the amount of electric charge an object has, usually in coulombs (C).
Coulomb and ampere:
A coulomb is a measure of electric charge.
Think of electric charge like tiny invisible “electric bits” that can move through wires or build up on objects.
• If you gather a certain amount of these electric bits, that amount is called 1 coulomb.
• If the charge starts moving, we measure how fast it moves using amperes (current).
• The rule connecting them is:
If 1 ampere flows for 1 second, the total charge that passes is 1 coulomb.
So:
Coulomb = amount of charge
Ampere = speed/flow of charge
Example:
If water is flowing in a pipe, the amount of water is like coulombs, and the speed of flow is like amperes.
