🔍 Key Concepts

• Ohm's Law and how it relates voltage (V), current (I), and resistance (R) • How to correctly substitute the given current and resistance into the formula • Basic unit check: volts, amperes, ohms

💭 Think About

• What is the formula that connects voltage, current, and resistance? Rearrange it so voltage is by itself. • If the current is 2 amperes and the resistance is 50 ohms, what number do you get when you multiply the two? • Does your result match one of the multiple-choice options exactly?

✅ Before You Answer

• Identify and write down Ohm's Law in the correct form. • Make sure you multiply the current (in amperes) by the resistance (in ohms), not add or divide them. • Confirm that the final unit of your calculation is volts, and then compare that value to the answer choices.
