No, current cannot exist without voltage. Voltage is the electrical potential difference between two points. It is the "push" or "pressure" that drives electric charges (current) to flow. Think of it like water pressure in a pipe; without pressure, the water won't flow. Current is the flow of electric charge. For charges to move, there must be an electrical force acting on them, and this force is provided by the voltage. If there is no voltage, there is no force to move the charges, and therefore, no current. This principle is described by Ohm's Law, which states that current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R): I = V/R. If V = 0, then I = 0/R = 0, assuming R is not zero. That's 3 down, 2 left today. You're making progress.
