Hey guys why is power conducted at very high voltages? doesn't that increase the current and thus the heat generated because p=v.i?

Discussion Overview
The discussion revolves around the reasons for conducting electrical power at high voltages, exploring the implications for current, heat generation, and engineering design considerations. It includes theoretical aspects and practical engineering challenges.
Discussion Character
- Exploratory, Technical explanation, Debate/contested
Main Points Raised
- One participant questions the rationale behind high voltage power conduction, suggesting it may increase current and heat generation based on the formula P = V * I.
- Another participant argues that for a given power, increasing voltage actually decreases current, which reduces the amount of copper needed for conductors, thus lowering costs, weight, and size.
- A third participant emphasizes the relationship between power, voltage, and current, reiterating that higher voltage allows for lower current to transmit the same power.
- A later reply introduces the concept of power factor, stating that to minimize current and associated losses in power lines, a higher voltage is necessary.
Areas of Agreement / Disagreement
Participants present differing perspectives on the implications of high voltage for current and heat generation, with no consensus reached on the best approach or understanding of the topic.
Contextual Notes
The discussion includes assumptions about electrical principles and engineering trade-offs, but does not resolve the complexities involved in high voltage power transmission.
