The symbol for current is:

Explanation:
Current is the flow of electric charges through a conductor, and in circuit notation that variable is represented by the letter I. That’s why this symbol stands for current. The other quantities use different symbols: voltage is denoted by V, resistance by R, and electric charge by Q. Knowing these helps you apply Ohm’s law and analyze circuits, since I = V/R ties current, voltage, and resistance together.
