The correct Answer is:
To solve the problem, we need to determine how the power \( P \) supplied by the transmission lines is proportional to the voltage \( V \) transmitted to our houses. ### Step-by-Step Solution: 1. **Understanding Power in Electrical Circuits**: The power \( P \) supplied in an electrical circuit can be expressed using the formula: \[ P = V \times I \] where \( V \) is the voltage and \( I \) is the current flowing through the circuit. 2. **Assuming Constant Current**: In the context of the problem, we assume that the current \( I \) flowing through the transmission lines remains constant. This means that any change in voltage \( V \) will directly affect the power \( P \). 3. **Expressing Power in Terms of Voltage**: Since \( I \) is constant, we can express the relationship between power and voltage as: \[ P \propto V \] This indicates that power is directly proportional to the voltage when the current is held constant. 4. **Conclusion**: Therefore, we conclude that the power \( P \) supplied by the transmission lines is proportional to the voltage \( V \) transmitted to our houses. ### Final Answer: The power \( P \) supplied by the transmission lines is proportional to the voltage \( V \). ---
