🔍 Key Concepts

• Ohm’s Law relationship between voltage (V), current (I), and resistance (R) • How to rearrange a simple formula to solve for an unknown • Checking that your units match: volts, amperes, ohms

💭 Think About

• What is the basic formula that links voltage, current, and resistance, and which symbol stands for each? • If you know the voltage and the current, how can you rearrange that formula to solve for resistance? • Once you calculate a numerical value, which of the choices is closest and has the correct unit?

✅ Before You Answer

• Write down Ohm’s Law clearly before doing any math • Make sure you divide the correct quantity by the other (don’t multiply them) • After calculating, confirm the result is in ohms and is a reasonable size given 90 volts and 3 amperes
