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.​

Asmall electric heater, immersed in 80g of water in a calorimeter of 40j/k raises the temperature from 10.5 degree celsius to 25 degree celsius in 12 minutes. using the same apparatus with 50g of oil instead of water, it is found that the temperature of oil rises from 7 degree celsius to 27 degree celsius in 10 minutes. find specific heat capacity of the oil.
