Which symbol represents electrical current?

Explanation:
Current is the flow of electric charge in a circuit, and the quantity is denoted by I. This is why Ohm’s law is written I = V / R, where V is voltage and R is resistance. The other symbols stand for different quantities: V for voltage, R for resistance, and P for power. Sometimes you’ll see the instantaneous current written as i(t), but the standard symbol used in most formulas is I. So the symbol that represents electrical current is I.
