🔍 Key Concepts

• Temperature coefficient of resistance (TCR) definition in basic electricity • Difference between positive and negative temperature coefficients • How resistance of common metals (like copper) changes with temperature

💭 Think About

• When something has a positive coefficient, does the related value go up or down as the other variable increases? • Think about a copper wire: if it gets hotter, what typically happens to its resistance? • If you understand what happens when temperature goes up, can you infer what must happen when temperature goes down?

✅ Before You Answer

• Be clear on what positive vs negative coefficient means in math/physics: does the quantity increase or decrease with the variable? • Check that your chosen option correctly describes behavior for increasing temperature, since that’s what the phrase focuses on. • Verify that any extra statement about decreasing temperature is consistent with the first part and not contradicting it.
