Electric Current Formula
The Formula
When to use: Current is like the flow rate of water in a pipe — how much charge passes a point each second.
Quick Example
What This Formula Means
The rate of flow of electric charge through a conductor. Measured in amperes (A).
Current is like the flow rate of water in a pipe — how much charge passes a point each second.
Worked Examples
