Q1) Design an electrical measurement device that can switch on an air cooler to work when the temperature is 25 C and the electrical power should be 220 V. Note the electrical power has reduced to 5V when it is 220 V by some circuits. You can use this signal m your device.

The manimum value of the altenating wotaye and curent are 400 U and 20A respectvely s a cieritoanected to a svita supply . The ristantanerus values of the veltnge and current are 283V and 10 A respectvely of fime t=0, beth icreasing pesitively. 4) Write dan the gapressom for vwltaga and curend at pmet. b).

Derive an expression for Vout as a function of Vin, where Vin is the nodes connected to the Waveform Generator signal. Show your equations below, either typed or a picture of your handwritten work.

Please try some part typing format..

Identify the states, inputs, and output • Show your work to get the dynamics • Present the state space model, including the state equations and output equation
