Problem 23.60
If the battery in (Figure 1 ) were ideal, lightbulb A would not dim when the switch is closed. However, real batteries have a small internal resistance, which we can model as the 0.3Ω resistor shown inside the battery. In this case, the brightness of bulb A changes when the switch is closed. Assume E=2.0 V.

Part A
How much power does bulb A dissipate when the switch is open?
Part B
How much power does bulb A dissipate when the switch is closed?

When market rates of interest rise after a fixed-rate security is purchased, the value of the now-below-market, fixed-interest payments declines, so the market value of the investment falls. On the other hand, if market rates of interest fall after a fixed-rate security is purchased, the fixed-interest payments become relatively attractive, and the market value of the investment rises. Assuming these price changes are not viewed as giving rise to an other-than-temporary impairment, how are they reflected in the investment account for a security classified as held-to-maturity?

HR Industries (HRI) has a beta of 1.9, while LR Industries's (LRI) beta is 1.0. The risk-free rate is 6%, and the required rate of return on an average stock is 13%. The expected rate of inflation built into rRF falls by 1.5 percentage points; the real risk-free rate remains constant; the required return on the market falls to 10.5%; and all betas remain constant. After all of these changes, what will be the difference in the required returns for HRI and LRI? Round your answer to two decimal places.

Explain why, if two mutually exclusive projects are being compared, the project that generates most of its cash flows in the beginning of its life might have the higher ranking under the NV criterion if the required rate of return is high, whereas the project that generates most of its cash flows toward the end of its life might be deemed better if the required rate of return is low. Would changes in the firms required rate of return ever cause a change in the IRR ranking of two such projects? Explain.
