Q.4 (a) Draw and label a gold leaf electroscope. Explain how such an instrument can be used to distinguish between an insulator, a poor conductor and a good conductor (b) Describe and explain what happens when the terminals of a charged capacitor are connected by a piece of copper wire (c) Plates were fixed on the top and bottom of a cubical box with each side equal to 2 cm. A capacitor was constructed out of this box by filling it with a suitable dielectric material. In an experiment with this capacitor, the charge stored was measured and the electric field between the plates was determined as the charging potential difference was varied. The results are tabulated below. Charge stored/uC 7.5 30 60 75 90 Electric 0.5 2.0 4.0 5.0 6.0 field/Vcm-1 Plot a suitable graph which can be used to determine the dielectric strength, and hence the capacitance of the capacitor used in this experiment. Calculate the total energy stored by the capacitor when the electric field is 400 V/m.
Compare wiring capacitors in series versus wiring them in parallel. Please answer the question in at least 10 sentences. Use paragraph form. Your answer should include the following points: • How much charge can you accumulate on each plate in series vs. in parallel? • How does the voltage compare across the plates in series vs. parallel? • How does the total capacitance compare? Which would you rather use and why? (I.e. which would be more economical if you were building, say, a computer?)

Q5 Choose Two only A) Explain briefly various theories of breakdown in liquid dielectrics. B) What are the requirements of a sphere gap for measurement of high voltages? Discuss the advantages and disadvantages of sphere gap for measurements. C) Determine the Townsend's first ionization coefficient if a steady current of 500 µA flows through the plane electrode separated by a distance of 0.4cm when a voltage of 10 kV is applied. A current of 25 µA flows when the distance of separation is reduced to 0.1 cm and the field is kept constant at the previous value. Find also the value of y if the breakdown took place when the gap distance was changed to 0.7 cm.
