Human Resistance vs. Circuit Conductors

Click For Summary

Discussion Overview

The discussion revolves around the phenomenon of electric shock experienced by humans when touching a circuit, despite the human body's higher resistance compared to circuit conductors. It explores concepts related to electrical resistance, current flow, and the implications of these factors in practical scenarios.

Discussion Character

  • Debate/contested, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants question the belief that electricity always follows the path of least resistance, suggesting that current flows through all available paths based on their resistance levels.
  • One participant notes that while the human body has higher resistance, it can still conduct enough current to induce a shock, as only a few milliamps are required for this effect.
  • Another participant mentions the concept of current division and provides a link for further reading, indicating that the discussion includes technical aspects of how current behaves in circuits.
  • There are references to calculating the ratio of wattage passing through different paths in a circuit, with an emphasis on the role of human resistance as a parallel resistance in the circuit.

Areas of Agreement / Disagreement

Participants express differing views on the nature of current flow and resistance. While some clarify and challenge the initial beliefs, there is no consensus on the implications of these concepts regarding electric shocks.

Contextual Notes

The discussion includes assumptions about the definitions of resistance and current flow, and the implications of these definitions on the understanding of electric shocks. Some mathematical steps and specific conditions under which these phenomena occur remain unresolved.

TL;DR
Why do I get electrically shocked when I touch a circuit knowing that the human body has a higher resistance than conductors in circuits and current tends to flow through the path of least resistance?
Have you ever wondered why you can get an electric shock when touching a circuit, even though the human body has a higher resistance than the conductors in circuits? It goes against my belief that electricity always follows the path of least resistance.

That belief is false. Current flows anywhere there is a path available, but it flows according to the resistance of the path; higher resistance means less current, lower resistance means higher current.

The resistance of the body may have a higher resistance than the circuit involved, but it only takes a few milliamps of current to induce a "shock".

You can work out the ratio of wattage that will pass through both paths of this circuit simultaneously.

Not a lot will pass through R2. But it won't be zero.

So I will be considered as a parallel resistance in the circuit

Exactly.
