4. (a) What is the purpose of 'short circuit' and 'open circuit' test of a transformer? Briefly describe the procedure for 'short circuit' test with necessary diagram. [3+5] (b) A 120-VA 130/13 V transformer is to be connected so as to form a step-up auto- transformer. The conventional two-winding transformer has series resistance and reactance of 1% and 8% per unit respectively. A voltage of 120V is applied to the autotransformer's primary. Calculate (i) secondary voltage of the transformer, (ii) Rating advantage in autotransformer mode of operation. (iii) Series impedance per unit in this mode of operation. [2+3+2]

Texts: For your selected and approved company, complete the following requirements. You may complete these in a separate document that is attached and/or copied into your response. For calculations, show inputs into the calculations as well as the results. For example, if I was calculating a Current Ratio, in my write-up I would write: "Current Ratio = Current Assets / Current Liabilities. For 2022, $400,000,000/$200,000,000 = 2.0. For 2021, $350,000,000/$225,000,000 = 1.56." Chapter 7 Read the summary of significant accounting policies in the notes to the financial statements. Locate the section on property and equipment. What depreciation method does the company use? What are the estimated useful lives for each of their asset categories? Find the Property and Equipment note. What are the cost and book value of property and equipment for the most recent year? What is the trend in depreciation expense for the past three years? Find the Intangible Assets note. What intangibles are listed? Chapter 8 Calculate the current ratio for the most recent year. Calculate the acid-test (quick) ratio for the most recent year. Analyze the results of your calculations, given what you know about the company and the information provided in their financial statements (see Notes to the Financial Statements) Chapter 9 Calculate the debt-to-equity ratio for the most recent year. Calculate the return on assets ratio for the most recent year. Does the return on assets exceed the cost of borrowing of approximately 4%? Review the balance sheet and debt note to the financial statements. Based on this information, how would you rate the bankruptcy risk of the company?
