Sir यूट्यूब में एक वीडियो देखा है यदि एक सुई को अंतरिक्ष से प्रकाश की चाल से पृथ्वी पर गिराया जाय तो यह कई परमाणु बम ब्लास्ट से ज्यादा खतरनाक होगी। कृपया इस पर एक शॉर्ट वीडियो बनाकर जानकारी दें। धन्यवाद 🙏🙏🙏🙏
Bilkul sahi because light ki speed prapt krne ke liye us needle ko infinite energy ki requiremen hogi jo earth se touch hote hi usme transfer ho jaygi... Aur jante ho wo needle earth ke aar-par nikal jaygi

सर जी आपके स्तर का विज्ञान का ज्ञान हासिल करने के लिए खान सर को शुरू से हाईस्कूल से लेकर BSc, MSc, PHD in Science & Bed इसके बाद ही एक अनुभवी विज्ञान शिक्षक कहलाएंगे ।। यहां तक पहुंचने को खान सर को फिर से जन्म लेना पड़ेगा ।।
Sir, my age is 55yrs . I am mechanical engineer. But I had dream to learn electrical engineering and I started learning through your videos. I have started making notes . The best part I like the most is free electron flows from cathode , which is negatively charged. Because students don't know how charge flows. Explanation towards solar cell excellent. Simple and we will never forget. Sir, I have one doubt. Can we see electron with help of any equipment.
इस टॉपिक को समझने के लिए आज तक न जाने कितने प्रयास किए गए थे हमसे लेकिन नही समझ पाए अब जाके आपसे इस टॉपिक को हम अच्छे से समझ पाए आपका बहुत बहुत धन्यवाद sir ❤❤ 🙏🙏
Very good explanations for pn junction,diode , photovoltaic cells, practical applications.keep making such informative videos. You are a great teacher of physics.
1:16:16 Depletion Layer in a Solar Cell--- Creation of Depletion Region--- Within a solar cell, the p-n junction forms a depletion region or layer. This layer is created due to the diffusion of charge carriers (electrons and holes) across the junction, leading to the establishment of an electric field. Function of the Depletion Layer--- The depletion layer acts as a barrier to the free movement of charge carriers. When the solar cell is not illuminated or under reverse bias, this region prevents the significant flow of current. Upon Illumination--- When sunlight strikes the solar cell, photons are absorbed, generating electron-hole pairs within the semiconductor material. These pairs are created primarily in the region close to the depletion layer. Charge Carrier Separation--- The electric field in the depletion layer separates the generated electron-hole pairs, causing electrons to move toward the n-side and holes toward the p-side of the junction. Assistance in Charge Collection--- The depletion layer facilitates the separation and movement of charge carriers in opposite directions. Forward bias applied across the cell helps in reducing the barrier of the depletion layer, enabling the separated charges to move more freely towards the respective terminals. Electricity Generation--- As explained earlier, the movement of these charge carriers in response to the electric field across the forward-biased p-n junction results in the generation of an electric current, which can be utilized to power external devices or circuits. The depletion layer's role is critical in the operation of a solar cell, particularly in facilitating the separation and movement of charge carriers generated by incident photons, contributing significantly to the conversion of solar energy into electrical energy.

Silicon, specifically, is a metalloid element that is commonly used in electronics and various industrial applications due to its semiconductor properties. For elements in the main groups Group 1 to 18 excluding the transition metals the last digit of group number may corresponds to the number of valence electrons. For instance Elements in Group 1 e.g. Hydrogen, Lithium, Sodium have 1 valence electron. Elements in Group 14 e.g. Carbon, Silicon, Germanium have 4 valence electrons. Elements in Group 17 e.g. Fluorine, Chlorine, Bromine have 7 valence electrons. This pattern continues until Group 18 Noble Gases where elements have full valence shells making them stable with the maximum number of valence electrons.
