Problems

1. Calculate the resistance, inductance, and capacitance for a 128-mil hard-drawn copper, open-wire line, with 12-inch spacing, and at 1000 cycles and 20° centigrade. Compare these values with those given in Table IV.

2. Calculate α, β, and Z₀ for the line of Problem 1, and at a frequency of 1000 cycles.

3. If the line of Problem 1 is 100 miles long, is terminated in its characteristic impedance, and the input testing power is one milliwatt at 1000 cycles, calculate the input voltage and current, and the received voltage, current, and power.

4. Repeat the calculations starting on page 227 at a frequency of 15 megacycles.

5. Repeat the calculations starting on page 228 at a frequency of 15 megacycles.
