In a DC circuit with V = 60 V and R = 15 Ω, what is the current?

Explanation:
Current follows Ohm’s law: I = V / R. With a voltage of 60 volts and a resistance of 15 ohms, the current is 60 ÷ 15 = 4 amperes. So the flow of charge is 4 A. In the circuit, voltage acts like pressure pushing charge through a resistor, and a larger resistance lowers the flow for the same voltage—this calculation shows that relationship directly. The other numbers would come from using a different ratio, but with these values the correct current is 4 A.
