Introduction
Today you will test your knowledge of circuits by trying to identify circuit elements concealed inside a black box. Each box may contain resistors, capacitors, inductors, diodes, and batteries or a combination of two or three of these circuit elements in series and/or in parallel with each other. Each box has two banana plugs for connecting the box to a circuit. Using techniques from previous labs, you should be able to determine what is in any of the black boxes. No screwdrivers allowed1.
Objectives
To review the properties of AC and DC circuits.
To practice using the DMM and oscilloscope to make electrical measurements.
To design your own experiments to test a hypothesis.
Prelab Questions
1. The voltage across which circuit element (resistor, capacitor. or inductor) increases as the frequency is increased? In your notebook sketch the expected curve of L vs. f for this element.
2. The voltage across which circuit element (resistor, capacitor, or inductor) decreases as the frequency is increased? Sketch V vs. f for this element.
3. The voltage across which circuit element (resistor, capacitor, or inductor) does not dependent on frequency? Sketch V vs. f for this element.

How much profit is earned
: The demand function for a good is given as Q = 10 – 2P, where Q = quantity demanded and P = the market price per unit of the good. The cost function is given as C = 8 + 0.5Q where C = total cost. If P = $3, how much profit is earned?

What is the breakeven quantity and total profit
: What is the total profit? What is the average cost per unit? What is the breakeven quantity (round up to the nearest whole unit)? If variable cost increases to $0.70, by how much will profit decrease (compared to your answer in part A)?

Computing service-hours depreciation
: The company acquired a machine on January 1 at an original cost of $60,000. The machine's estimated residual value is $10,000, and its estimated life is 10,000 service hours. The actual usage of the machine was as follows: Year 1, 2,000 hours; Yea..
