भारतीय रसायन के पिता आचार्य प्रफुल्ल चंद्र रे की जयंती पर व्याख्यान का आयोजन

भारतीय रसायन के पिता आचार्य प्रफुल्ल चंद्र रे की जयंती पर व्याख्यान का आयोजन विज्ञान भारती उदयपुर इकाई एवं बीएन कॉलेज ऑफ फार्मेसी, बीएन विश्वविद्यालय के संयुक्त तत्वावधान में कार्यक्रम सम्पन्न उदयपुर, 2 अगस्त। भारतीय रसायन के पिता आचार्य प्रफुल्ल चंद्र रे की जयंती के अवसर पर विज्ञान भारती उदयपुर इकाई (चित्तौड़ प्रांत) एवं बीएन कॉलेज ऑफ फार्मेसी, बीएन विश्वविद्यालय के संयुक्त तत्वावधान में एक विशेष व्याख्यान का आयोजन किया गया। कार्यक्रम का उद्देश्य आचार्य पी.सी. रे के वैज्ञानिक योगदान एवं उनके देशभक्ति से ओतप्रोत जीवन पर प्रकाश डालना था। ज्ञातव्य है कि भारत की पहली फार्मा कंपनी आचार्य रे ने ही बंगाल केमिकल एंड फार्मास्यूटिकल्स लिमिटेड, कोलकाता में 1901 में प्रारंभ की थी। कार्यक्रम में विज्ञान भारती के उद्देश्य एवं गतिविधियों की जानकारी डॉ. अमित गुप्ता द्वारा दी गई। आचार्य पी.सी. रे के जीवन और कार्यों पर मुख्य व्याख्यान डॉ. लोकेश अग्रवाल द्वारा प्रस्तुत किया गया। उन्होंने बताया कि कैसे आचार्य रे ने विज्ञान को समाज की सेवा का माध्यम बनाया और रसायन विज्ञान में भारत को आत्मनिर्भर बनान...

Dipole in electric field | Electrostatics


    Electric field

  • The space around a charged particle in which another charge experience a force is known as electric field.
  • Electric field due to a circular loop of charge

  • This is a linear charge distribution in which the charge is distributed along the circumference of the ring or circular loop.
  • If observation point lies on the centre of the loop, then the electric field internsity at this point i.e., at the centre of the loop will be zero.
  • If observation point lies very far from the centre of the loop then the value of electric field will be same as the electric field due to a point charge. It means in this case the circular loop behaves as a point charge for the observation point.
  • Electric field due to an infinitely long straight uniformly charged wire

  • In this article the charge is distibuted along the length of the wire.
  • The electric field at any point due to infinitely long straight wire varies inversely with distance from the wire.
  • NOTE

  • The present lecture is a bilingual lecture, in which every step is explained in Hindi and in English language. Electric field is very important in electrostatics. In the present lecture the electric field due to circular loop of charge, and the electric field due to an infinitely long straight wire is also explained in a well systematic way.
