If a circuit has V = 9 V and R = 3 Ω, what is the current I?

Explanation:
Current is the rate at which charge flows, and Ohm’s law ties it to voltage and resistance: I = V / R. With a voltage of 9 volts across a 3-ohm resistor, the current is 9 divided by 3, which equals 3 amperes. So the current is 3 A. This shows how the values interact: increasing voltage or decreasing resistance raises the current, while decreasing voltage or increasing resistance lowers it.
