d. b. You are designing an electronic circuit elemtn made of 23 mg of silicon. The electronic current through it adds energy at the rate of 7.4 mW = 7.4 x 10-3 J/s. If your design doesn't allow any heat transfer out of the element, at what rate does its temperature increase? The specific heat of silicon is 7.5 J/kg K. [3] Ans: 0.46 K/S​
