Calculate the maximum current that may be allowed to flow through a 1N755 Zener diode at device temperatures of 50oC and 100 oC. 1N755 Zener diode has VZ = 7.5V, PD = 400 mW at 50oC, and

the derating factor = 3.2 mW/ oC.​

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics? a. the first law describes how thermal energy is conserved but not the direction it moves. b. the first law describes the direction thermal energy moves but not how it is conserved. c. the first law describes how thermal energy can be created but not how it can be destroyed. d. the first law describes how thermal energy can be destroyed but not how it can be created.
