భావన:
 
గాస్ నియమం:
  • ఈ నియమం ప్రకారం, గౌసియన్ ఉపరితలం అని పిలువబడే మూసిఉన్న ఉపరితలంతో అనుసంధానించబడిన మొత్తం ఫ్లక్స్ మూసిఉన్న ఉపరితలం ద్వారా ఆవరించి ఉన్న ఆవేశానికి 1/εo రెట్లు ఎక్కువ.

\(\Rightarrow \phi=\oint \vec{E}.\vec{dA}=\frac{Q}{\epsilon_o}\)

  • ఈ నియమం అన్ని మూసివేసిన ఉపరితలాలకు వర్తిస్తుంది.
వివరణ:
  • ఈ నియమం ప్రకారం, గౌసియన్ ఉపరితలం అని పిలువబడే మూసిఉన్న ఉపరితలంతో అనుసంధానించబడిన మొత్తం ఫ్లక్స్ మూసిఉన్న ఉపరితలం ద్వారా ఆవరించి ఉన్న ఆవేశానికి 1/εo రెట్లు ఎక్కువ.
  • కాబట్టి ఈ నియమం అన్ని మూసిఉన్న ఉపరితలాలకు వర్తిస్తుంది. అందువల్ల, ఎంపిక 1 సరైనది.
