In science, the word "current" refers to the flow of a medium. The specific definition depends on the context:

Definition (Electricity)

Current is the rate of flow of electricity. The unit of current is the ampere (A) which is defined as 1 ampere = 1 coulomb per second.

Definition (Fluid)

Current is the flow of a fluid, such as a gas or liquid. Air currents refer to air, while ocean currents and rip currents refer to water. A typical unit is meters per second (m/s).

Definition (Quantum Mechanics)

In physics, a current may refer to a probability current, which is also called a probability flux. This is a quantity that described the probability of flow in terms of unit time per unit area.
