Measure of the rate of flow of electrical current is

The rate of flow of electric current is the current, measured in amperes (amps). Ohm’s law says current I equals voltage V divided by resistance R, so I = V/R. That means current can be described as volts divided by ohms, which matches the units given for amps. The other terms describe different quantities: ohms measure resistance, not flow; voltage is the driving potential, not the rate; watt is a unit of power (volts times amps), not the rate of flow. For example, 9 volts across 3 ohms yields 3 amps of current.
