In the circuit shown in the following figure(Figure 1) the capacitor has capacitance 19 μF and is initially uncharged. The resistor R0 has resistance 11 Ω. An emf of 84.0 V is added in series with the capacitor and the resistor. The emf is placed between the capacitor and the switch, with the positive terminal of the emf adjacent to the capacitor. The small circuit is not connected in any way to the large one. The wire of the small circuit has a resistance of 1.1 Ω/m and contains 25 loops. The large circuit is a rectangle 2.0 m by 4.0 m, while the small one has dimensions a = 13.0 cm and b = 18.0 cm. The distance c is 5.0 cm. (The figure is not drawn to scale.) Both circuits are held stationary. Assume that only the wire nearest the small circuit produces an appreciable magnetic field through it. Figure 1 of 1 Part A The switch is closed at t = 0.

Three balls are attached by rigid rods of negligible mass as seen in the diagram below. This system is placed on a table which lies in the horizontal plane (noting that the view shown below is the "bird's eye" view of the table). Balls A and B each have a mass of 0.2 kg, while Ball C has a mass of 0.8 kg. Note that the diagram is not to scale. (a) Locate the x and y coordinates of the ball and rod system's centre of mass, G, within the coordinate system shown. (b) At the instant the 10 N force is applied as shown in the diagram, calculate the instantaneous linear acceleration of the mass centre. (c) At the instant the 10 N force is applied, calculate the instantaneous angular acceleration of the ball and rod system, α.

In this question, you are asked to find the effective transconductance (Gm) and the resistance into the drain (Rx) of a common-source amplifier with source degeneration. Based on the results, the voltage gain of a common-source amplifier with source degeneration will be evaluated a) The figures shown below are a circuit to find the effective transconductance (G) of the NMOSEFT with source degeneration (left) and its corresponding small-signal circuit (right). It is noted that the output is shorted to VDD (ac grounded) since the definition of effective transconductance is the ratio between the short-circuit output current and the input signal voltage. Prove that Gm is given by Gm = id/vin = gm/1+gmRs In this calculation, the current passing through ro can be neglected since, in general, ro is very large when the NMOSFET operates in saturation region and so this current is very small. Thus, the indication of id is the current of the voltage-controlled current source (gmvgs) only. b) The figure shown below is the method to evaluate the resistance looking into the drain (i.e. Rx) of a source-degenerated NMOSFET. The circuit is shown on the left while the equivalent small-signal modeling is shown on the right. It is noted that the bias condition (VBiAS) is set so that the values of gm and ro, can be defined. Moreover, there is no input signal (i.e. Vin = 0) since we would like to see the value of Rx which is due to the circuit only but not due to the external effect. Based on the above small-signal model, prove that RX = ro(1 + gmRS) The complete common-source amplifier with source degeneration is shown below. c) The complete common-source amplifier with source degeneration is shown below. Prove that the voltage gain of this amplifier is given by v. Vin Explain the reason(s) why the voltage gain is negative. What is the physical meaning of negative voltage gain?
