🔍 Key Concepts

• Electrical resistance in basic circuit theory • Ohm’s Law: relationship between voltage, current, and resistance • How power dissipation relates to resistance (P = I²R or P = V²/R)

💭 Think About

• Think about the formal definition of resistance in terms of how it relates voltage and current—what role does it play in Ohm’s Law? • Consider whether resistance is directly defined by its unit of measurement, or if the unit is just one characteristic of it. • Ask yourself: does resistance both determine how much power is lost as heat in a component and also serve as the proportionality factor between voltage and current?

✅ Before You Answer

• Verify how Ohm’s Law is written and what quantity sits between voltage and current. • Confirm the unit used to measure resistance and whether that alone is a complete definition. • Check how power loss in a resistor depends on resistance using formulas like P = I²R or P = V²/R and see which statements accurately describe resistance.
