Engineering

1. What is the resistance of a copper wire 200 ft long and 0.02 in. in diameter (T = 20 °C)?

2. A wire 1000 ft long has a resistance of 0.5 kΩ and an area of 94 CM. Of what material is the wire made (T = 20 °C)?

3. a. Is there an overlap in coverage between 20% resistors? That is, determine the tolerance range for a 10 Ω 20% resistor and a 15 Ω 20% resistor, and note whether their tolerance ranges overlap.

b. Repeat part (a) for 10% resistors of the same value.

4. Find the color code for the following 10% resistors:
a. 68 Ω b. 0.33 Ω c. 22 kΩ d. 5.6 MΩ

5. If the resistance between the outside terminals of a linear potentiometer is 10 kΩ, what is its resistance between the wiper (movable) arm and an outside terminal if the resistance between the wiper arm and the other outside terminal is 3.5 kΩ?
