Using Ohm's law, what is the current in amperes of a 120-volt circuit with a resistance of 60 ohms?

• A. 1.5 amperes
• B. 2.0 amperes
• C. 2.5 amperes
• D. 3.0 amperes

Answer: (B)

To find the current in a circuit using Ohm's law, you apply the formula I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. In this case, you have a voltage (V) of 120 volts and a resistance (R) of 60 ohms. Plugging these values into the formula gives: I = 120 volts / 60 ohms = 2 amperes. Thus, the current in the circuit is 2.0 amperes, which corresponds to the correct answer. This understanding of Ohm's law is crucial for various applications in electrical circuits, ensuring that calculations of current, voltage, and resistance are accurately conducted.
