Lower Resistance vs. Higher Resistance in Batteries
Lower Resistance vs. Higher Resistance in Batteries
Lower resistance is better for battery efficiency. Here's why:
Why Lower Resistance Is Better
Improved Power Delivery:
- Lower resistance allows more current to flow with minimal voltage drop. This ensures efficient energy transfer to the load.
- High resistance reduces the power the battery can deliver, especially during high-demand scenarios.
Reduced Heat Generation:
- Heat is generated according to Joule's law: P=I2×R.
- Lower resistance minimizes heat loss, improving energy efficiency and preventing thermal stress.
Better Voltage Stability:
- Batteries with low internal resistance maintain a more stable voltage under load, which is critical for sensitive electronics or high-power applications.
Increased Energy Efficiency:
- Lower resistance ensures that more of the battery’s stored energy is used by the load rather than being wasted as heat.
Longer Battery Life:
- Excessive heat from high resistance accelerates degradation, reducing battery lifespan.
- Lower resistance helps maintain stable chemical reactions, preserving the battery’s capacity over time.
Effects of High Resistance
Energy Loss:
- High resistance leads to greater energy dissipation as heat, reducing overall efficiency.
Voltage Drop Under Load:
- Significant voltage drops can occur when the battery is under high current demand, impacting device performance.
Thermal Management Challenges:
- Increased heat generation requires robust cooling systems, especially in high-capacity batteries like those in electric vehicles (EVs).
Decreased Power Output:
- High internal resistance limits the battery's ability to provide high currents, reducing its power output.
How Resistance Relates to Battery Health
- New batteries typically have low resistance, ensuring optimal performance.
- Aging batteries develop higher resistance due to chemical degradation, electrode wear, and electrolyte breakdown.
Ideal Scenario
A battery with low resistance ensures:
- High efficiency
- Minimal energy loss
- Extended lifespan
- Better thermal management
Note: While low resistance is generally desirable, there is an optimal range based on the battery chemistry and application. For example:
- Lithium-ion batteries typically have internal resistances in the milliohm range.
- If resistance is too low, it could indicate a short circuit, which is dangerous.
In conclusion, lower resistance is good for battery efficiency, performance, and longevity.

कृषि ड्रोन/Agricultural Drone
कृषि ड्रोन
कृषि ड्रोन एक बैटरी संचालित उपकरण है जो खेतों में दवा के छिड़काव, बीज या खाद छिड़काव के काम आता है और यह दो तरीके से काम करता है इस ड्रोन को ऑटोनॉमस या मैन्युअल मॉड में उड़ा सकते हैं ज्यादातर कृषि ड्रोन 10 लीटर वेरिएंट में आते हैं कुछ एक कंपनियां 16 लीटर या 15 लीटर या 30 लीटर वेरिएंट में भी ड्रोन बनती है
कृषि ड्रोन के लाभ
- कृषि ड्रोन एक नजदीकी रूप से खेती करने के काम आता है
- कृषि ड्रोन दवा का छिड़काव एक समान रूप से पूरे खेत में करता है और केमिकल्स को खराब होने से बचाता है
- यह कम पानी में दवा का छिड़काव करके पानी की बचत करता है जहां पर पुराने तरीके से एक एकड़ में छिड़काव करने के लिए लगभग 100 लीटर पानी की जरूरत होती है इससे 10 लीटर पानी में ही एक-एक कर का छिड़काव हो जाता है
- यह दवा की छिड़काव करते समय नुकसानदायक दवा को हमारे अंदर जाने से बचाता है
- यह एक एकड़ फसल का छिड़काव 5 से 6 मिनट में करके किसानों के समय का भी बचत करता है
- यह खेतों में यह खेतों में रोग के विश्लेषण और रोग के बारे में पता लगाने के काम आता है
कृषि ड्रोन खरीदते समय किन-किन बातों का ध्यान रखना चाहिए
- नागरिक उड्डयन महानिदेशालय (DGCA) द्वारा जारी प्रमाण पत्र - यह भारत सरकार का वैधानिक निकाय है जो ड्रोन, हवाई जहाज उड़ने के संबंध में नियम बनाते हैं आपको ड्रोन खरीदते समय यह ध्यान में रखना है कि जो ड्रोन खरीद रहे हो औरनागरिक उड्डयन महानिदेशालय द्वारा प्रमाणित हो.
- बैटरी को पूरा चार्ज करने के बाद ड्रोन कितने समय तक उड़ सकता है - यह एक बहुत महत्वपूर्ण बिंदु है इससे हमें पता चलता है कि एक बार बैटरी को पूरी चार्ज करने के बाद ड्रोन कितने समय तक उड़ के कितने एकड़ की फसल के ऊपर दवा का छिड़काव कर सकता है यह इस बात पर भी निर्भर करता है कि ड्रोन कितनी ऊंचाई पर उड़ रहा है कितना पेलोड लेकर उड़ रहा है कौन से मोड में उड़ रहा है
- सर्विस एवं मरम्मत केंद्र - यह यह जांच करना बहुत ही महत्वपूर्ण है कि जो आप ड्रोन खरीद रहे हैं उसकी सर्विस और मरम्मत केंद्र आपके घर से कितनी दूर है और कितनी से यह उपलब्ध हो सकती है तो जब भी आप ड्रोन खरीद रहे हैं तो आप इसकी जांच अवश्य ही कर ले
- ड्रोन प्रशिक्षण - एक महत्वपूर्ण बिंदु है आपको ड्रोन उड़ने के लिए नागरिक उद्द्यान्न निदेशालय द्वारा एक प्रमाण पत्र की आवश्यकता होती है यह प्रमाण पत्र नागरिक उदाहरण निदेशालय या उसके द्वारा सर्टिफाइड एजेंसीज प्रशिक्षण के बाद देती हैं अगर आप क्रोम खरीदने की योजना बना रहे हैं तो आप यह निश्चित करें कि आपके पास ड्रोन उड़ने का लाइसेंस हो.
- ड्रोन की विशेषताएं - यह एक महत्वपूर्ण बिंदु है जब भी हम ड्रोन खरीद रहे हैं तो हमें यह जांच करना बहुत जरूरी है कि जो ड्रोन आप खरीद रहे हैं उसमें क्या-क्या विशेषताएं हैं उससे आपको क्या-क्या फायदा हो सकता है
- जब आपड्रोन खरीद रहे हैं तो एक और महत्वपूर्ण बिंदु की जांच करनी है कि आप ड्रोन को कितना आसानी से उड़ा सकते हैं ड्रोन को उड़ाने के लिए बहुत लंबी प्रक्रिया से तो नहीं जाना है यह सारी चीज देखना अनिवार्य रूप से जरूरी होता है
Agricultural Drone Overview
An agricultural drone is a battery-powered device designed for spraying pesticides, seeds, or fertilizers across fields. These drones can operate in either autonomous or manual mode and typically come in 10-liter capacities. Some models are available in 15, 16, or 30-liter versions.
Benefits of Agricultural Drones
- Agricultural drones are essential tools for precision farming.
- They ensure uniform application of chemicals across the entire field, reducing waste and preventing spoilage.
- By using less water compared to traditional methods—where around 100 liters are needed per acre—drones use only about 10 liters to achieve the same result.
- This method also minimizes the risk of chemical exposure to humans during application.
- Drones significantly reduce the time required for spraying, covering an acre in just 5 to 6 minutes.
- They can also be used for field analysis to detect and assess diseases.
Key Considerations When Purchasing an Agricultural Drone
Certification: Ensure the drone is certified by the Directorate General of Civil Aviation (DGCA), the Indian government body responsible for drone and aircraft regulations.
Flight Time and Coverage: Check the drone’s flight duration on a full charge and its capacity to cover acres of crops. This varies based on flying altitude, payload, and operational mode.
Service and Repair: Verify the proximity and availability of service and repair centers for the drone you’re considering.
Training and Certification: To operate a drone, you need a license from the Directorate of Civil Aviation or an accredited agency. Ensure you have or will obtain the necessary certification.
Features: Assess the drone's features to ensure they meet your needs and provide the benefits you seek.
Ease of Use: Evaluate how user-friendly the drone is and whether the flying process is straightforward or requires extensive setup.
When choosing an agricultural drone, considering these factors will help you select the most suitable model for your needs and ensure efficient and effective use.
