Question
**Transcription and Diagram Explanation** **Text:** "1 AWG copper wire with 7 strands (diameter of each strand is 0.1037”) has a resistance of 0.70 Ω per mile at 25°C and 60Hz. Consider power transmission schemes A and B. Assume: - \( V_s = 120 \, V \, \text{RMS} \) - \( N_1 = 1 \) - \( Z_L = 4.0 + j0.0 \, \Omega \) - Transmission line is 19 miles long and the temperature outside is 25°C." **Diagram Explanation:** The image consists of two diagrams labeled A and B, representing different power transmission schemes. - **Scheme A:** - This is a simple circuit layout with a voltage source labeled \( V_s \) connected to a transmission line labeled \( Z_{\text{line}} \), which then connects to a load denoted as \( Z_L \). - **Scheme B:** - This diagram includes a transformer connected to the voltage source \( V_s \). The transformer steps up the voltage by a factor of 1:N and then steps it down by N:1 before reaching the load \( Z_L \). The transmission line \( Z_{\text{line}} \) is depicted between the transformer outputs and the load. Each diagram illustrates how power is transmitted from the source to the load, either directly through a line or through a transformer to adjust the voltage levels during transmission.
