QUESTION: Which statement is true about the effects of ambient temperature on solid state devices? POSSIBLE ANSWERS: A solid state device is more likely to withstand excessive cold than excessive heat. The typical failure rate for a solid state device is $35^{\circ }C(95^{\circ }F)$ The failure rate for a solid state device doubles for every $10^{\circ }C$ that the temperature rises.
