What is the circuit resistance in ohms if the applied voltage is 48 volts and the current is 0.5 amperes?

• A. 24Ω.
• B. 56Ω.
• C. 96Ω.
• D. 144Ω.

Answer: (C)

To determine the circuit resistance in ohms, you can use Ohm's law, which states that voltage (V) is equal to the product of current (I) and resistance (R). This relationship can be expressed with the formula: V = I × R. By rearranging this formula to solve for resistance, we get: R = V/I. In this case, the applied voltage is 48 volts and the current is 0.5 amperes. Plugging these values into the formula provides: R = 48 volts / 0.5 amperes, R = 96 ohms. The correct calculation leads to a resistance of 96 ohms, confirming that this is the right answer. It reflects the relationship between current, voltage, and resistance in an electrical circuit based on Ohm's law.
