2-) In the following AC-chopper circuit, the power transferred to the load is 1 kW, the Triac gate voltage is 1.2 V, and the breaking voltage of DIAC is 2 V. According to this; a. Calculate the parameter that is not given in the circuit (sin(2*n) = 0.9*n and take the source voltage for capacitor charging is Vmain(max),sin(n)) b. Plot the change of load voltage for one period in the time domain. C₁ 1901F 402 RY 2204 50HZ
