Question 9.7:
A table shows voltage (V) and current (I) readings for a resistor at 0°C and 100°C. Explain why the resistance increased at higher temperature.
Model answer:
At higher temperatures, metal ions in the resistor vibrate more vigorously. This increases collisions with free electrons, hence increasing resistance. This is consistent with the positive temperature coefficient of metals. Model Answer Description: A battery symbol connected to
