The device yields the data given in the table below, with vt and it defined in the figure next to it. vt in [V]it in [mA]03.5-0.242-0.560a) Find the model for this device, and draw it, labelling terminals a and b , and showing the values of the current source and resistor. b) Two such devices are connected in the circuit below. Find iX. Room for extra work 4) (25 Points) In the circuit shown, the voltmeter and ammeter are based on dеArsonval meter movements rated at 100[mV], 2[mA]. The voltmeter reads 3[V] full scale, and the ammeter reads 50[mA] full scale. a) If you take the ratio of the voltage read by the voltmeter, to the current read by the ammeter, will you get the value of RX? Defend your answer. b) Would this method of measuring resistances work if the voltmeter and ammeter were ideal? Explain your answer.

Draw your equivalent, labeling terminals a and b . 2Write an expression for the power absorbed by the voltage source as a function of time. You do not need to simplify your answer, but there can not be unknown variables in the expression. (In other words, the only variable in your expression should be t, for time.) You may assume that the energy stored in the inductor and the energy stored in the capacitor are zero at t = 0. vS(t) = 5 sin(10[rad/s] t) [V].The voltmeter is a 100[V] full scale voltmeter, made using a 50[mV], 1[mA] dеArsonval meter movement.
