This diagram shows a piece of silicon of width 32 mm and length 36 mm. The resistance of the silicon between the points P and Q is 1.1 MΩ. Silicon has a resistivity of 2.3 × 10³ Ω m.

a. Calculate the thickness of the piece of silicon.

b. Calculate the current that would pass through the silicon if a potential difference of 12 V were applied across P and Q.

c. Describe how the current would change if it were large enough to cause the silicon to become significantly warmer.
