o Section 31.9 The Series RLC Circuit

A generator is to be connected in series with an inductor of L = 2.00 mH and a capacitance C. You are to produce C by using capacitors of capacitances C1 = 4.00microF and C2 = 6.00 microF, either singly or together. What resonant frequencies can the circuit have, depending on the value of C?

You are given four capacitors of capacitance 2.0µF each. How manydi?erent
e?ective capacitors can you make with them, using one, two, three,or all four in dif-ferent con?gurations ( in series and/or inparallel ), and what are their capacitances?

Suppose the 6-month S&P 500 futures price is 1,399.25, while the cash price is 1,370.48. What is the implied dividend yield on the S&P 500 if the risk-free interest rate is 5 percent?

Suppose today is July 1 and that you own the S&P 500 and the current price is 370. You have achieved large gains over the past six months which you would like to lock in through the end of the year. Suppose the dividend yield on the S&P 500 is 3.3%, the volatility is 15% and the interest rate is 7%.
