The formula for 1 ampere (A) is based on the definition of electric current. In simple terms:
1 Ampere is the flow of 1 coulomb of charge per second.
Mathematically, this can be expressed as:
\[
I = \frac{Q}{t}
\]
Where:
- \( I \) is the electric current in amperes (A)
- \( Q \) is the electric charge in coulombs (C)
- \( t \) is the time in seconds (s)
So, for 1 ampere, you have:
\[
1 \, \text{A} = \frac{1 \, \text{C}}{1 \, \text{s}}
\]
This means that if 1 coulomb of charge passes a point in a circuit every second, the current is 1 ampere.
