If a 60-ohm resistor is connected to a 230-volt supply, the current is approximately:

• A. 3.83 A
• B. 0.39 A
• C. 23 A
• D. 230 A

Answer: (A)

Current in a circuit follows Ohm's law: I = V / R. With 230 volts across a 60-ohm resistor, the current is 230 ÷ 60 ≈ 3.83 amperes. This shows how resistance sets the amount of current for a given voltage—the higher the resistance, the smaller the current; the lower the resistance, the larger the current. For context, 0.39 A would come from about 600 ohms, 23 A from about 10 ohms, and 230 A from about 1 ohm. So the 60-ohm resistor yields roughly 3.83 A.
