Cavity inside a current carrying conductor

Click For Summary
SUMMARY

A cavity inside a current-carrying conductor does not electrify a person inside it due to the low resistivity of conductors, which results in minimal voltage differences across the cavity. Consequently, no significant current flows through an individual within the cavity, ensuring their safety. This principle applies similarly in scenarios such as being inside a car with fallen electrical cables, where remaining inside is safer than attempting to exit.

PREREQUISITES
  • Understanding of electrical conductivity and resistivity
  • Knowledge of current flow in conductors
  • Familiarity with electrical safety protocols
  • Basic principles of electromagnetism
NEXT STEPS
  • Research the properties of conductors and their resistivity
  • Study the effects of electric fields within cavities
  • Learn about electrical safety measures in emergency situations
  • Explore the principles of electromagnetism related to current flow
USEFUL FOR

Electrical engineers, safety professionals, and anyone interested in understanding the behavior of electric fields in conductors and safety protocols in electrical emergencies.

suppose there is a cavity inside a current carrying conductor.if anyone is inside the cavity he will be electrified or not?what's the explanation of this problem?

Hi and welcome.
Conductors, especially those that are used to actually carry current, have very low resistivity so no two parts of this cavity will have more than a very few mV across them. So (assuming he can hold his breath or that there are some holes) the person would be fine because no appreciable current could be flowing through him.

If you find yourself in a car on which an electricity cable has fallen, you would be safe as long as the sparks don't cause a fire. Best advice would probably be to stay there until someone rings the electricity company and the power is turned off. Trying to step down to the ground could be risky, though.
