If a circuit has a supply of 115 V and a resistance of 60 Ω, the current is approximately how many amperes?

• A. 10 A
• B. 0.5 A
• C. 2 A
• D. 5 A

Answer: (C)

Ohm’s law relates current, voltage, and resistance: I = V / R. With 115 V and 60 Ω, the current is I = 115 / 60 ≈ 1.92 A. Since the options are approximate, about 2 amperes is the best match. The other currents would require different voltages (for example, 10 A would need around 600 V, 0.5 A would need around 30 V, and 5 A would need around 300 V), which don’t fit a 115 V supply.
