If Voltage is 120 V and Resistance is 60 Ω, what is the current according to Ohm's law?

• A. 2 A
• B. 1 A
• C. 0.5 A
• D. 4 A

Answer: (A)

Think of current as the result of voltage driving through resistance. Ohm's law says I = V / R. With 120 volts and 60 ohms, you divide 120 by 60, which gives a current in the amperes. This matches the option that describes the current as two amperes. The relationship shows why the current scales with voltage and inversely with resistance: higher voltage or lower resistance increases current, and vice versa.
