Resistance can be calculated by:

Resistance can be calculated by:

• A. V divided by P
• B. E divided by I
• C. P divided by I
• D. V divided by I

Answer: (D)

The calculation of resistance is based on Ohm's Law, which states that resistance (R) is equal to voltage (V) divided by current (I). This relationship is fundamental in electrical theory and expresses how much opposition a circuit offers to the flow of electric current. When you use the formula R = V / I, you can determine how much voltage is needed to push a certain amount of current through a resistor. This principle is crucial in circuit design, troubleshooting, and understanding how different components in a system interact. Understanding this formula allows you to calculate necessary values for designing electrical circuits and ensuring they operate safely and effectively. The other choices involve different relationships tied to electrical power and circuits but do not accurately reflect the calculation of resistance. Therefore, knowing that resistance is calculated specifically as voltage divided by current helps reinforce foundational concepts in electrical theory.
