Question 5a) The resistance of a coil aluminum wire at 21°C is 2102. The temperature of thewire is increased and the resistance rises to 2402. If the coefficient of resistanceof aluminum is 0 .0039/ºC at 21°C, determine the temperature to which the coilhas risen.b) A coil consist of 2000 turns of copper wire having a cross sectional area of0.8mm?. The mean length per turn is 80 cm and the resistivity of copper is 0.02µ2-m. Find the resistance of the coil and power absorbed by the coil when connectedacross 110V D.C supply.c) A new manufacturing piant which operates on parameters such as temperatureand pressure, has been procured by your company. In the operational manual isstated “if one or more than one parameter exceeds the safe value, a protectivemeasure is needed to be done". As an engineer, design a schematic diagram usingan OR gate to detect the exceed parameter and explain how it will produce acommand signal for the system to take the required action.
