In the circuit with an ideal operational amplifier given in Figure 2. a) Express the voltage VO in terms of the voltage Vk. b) Taking \[ \boldsymbol{V}_{\boldsymbol{k}}=\frac{\mathbf{1}}{2} \cos (2 \pi 50 t) V \] , plot \( \mathrm{VO}(\mathrm{t}) \) and \( \mathrm{Vk}(\mathrm{t}) \) on the same graph. Figure 2 In the alternating current circuit shown in Figure 1, \[ \operatorname{vS}(t)=\sqrt{2} 200 \cos \left(t-30^{\circ}\right) V \] Find the active power, reactive power, apparent power and power factor of the load.
