Which symbol represents current in Ohm's law?

Explanation:
Current is the rate at which electric charges flow, and in Ohm's law it is shown by the symbol I. Ohm's law ties voltage, current, and resistance together with V = I R, so you can also express current as I = V / R. This means increasing voltage or decreasing resistance increases current. The other symbols represent different quantities: V is voltage, R is resistance, and P is power (which relates to voltage and current via P = V I or P = I^2 R). So the symbol for current in Ohm's law is I.
