What is the SI unit for current?

Explanation:
Current is the rate at which electric charge flows past a point in a circuit. The SI unit for that rate is the ampere (A), defined as one coulomb of charge passing a point every second. This makes sense because more charge per second means a larger current. The volt measures electric potential difference, the ohm measures resistance, and the watt measures power. These relate through I = V / R and P = V × I. For example, with 3 volts across a 1-ohm resistor, the current is 3 amperes and the power is 9 watts.
