What is the resistance in a circuit where the current is 5.8 amperes and the voltage is 12 volts?

• A. 1.50 ohms
• B. 2.06 ohms
• C. 2.43 ohms
• D. 3.00 ohms

Answer: (B)

To find the resistance in a circuit, Ohm's Law is applied, which states that resistance (R) is equal to voltage (V) divided by current (I). The formula is expressed as R = V / I. In this scenario, the current is 5.8 amperes and the voltage is 12 volts. Substituting these values into the equation gives: R = 12 volts / 5.8 amperes. Calculating this results in: R = 2.06896551724. When rounding to two decimal places, this value is approximately 2.07 ohms, which aligns closely with the provided option of 2.06 ohms. This option is therefore the correct choice as it accurately reflects the mathematical relationship dictated by Ohm's Law and the given circuit parameters. Maintaining precision in calculations is essential, as small deviations can impact the interpretation of electrical performance.
