In daily life, the heating effect of electric current is used in which of the following?
रोज़मर्रा की जिंदगी में, विद्युत धारा के ऊष्मा प्रभाव का इस्तेमाल इनमें से किसमें किया जाता है?
Detailed Solution & Logic
Electric heater, electric iron, and fuse/विद्युत हीटर, विद्युत इस्त्री और बल्ब
📖 Explanation
The heating effect of electric current (also called Joule heating) occurs when electric current passes through a conductor and produces heat due to resistance.
Applications in daily life include:
Electric heater – Converts electric energy into heat to warm rooms.
Electric iron – Heats up to press clothes.
Fuse – Melts when current exceeds limit, protecting the circuit.
Other options explained:
LED and torch – Work due to the flow of current producing light, not heat.
Electric fan and motor – Convert electrical energy to mechanical energy, not primarily heat.
Electric bell and buzzer – Produce sound, not heat.
विद्युत धारा का ऊष्मा प्रभाव तब होता है जब किसी चालक में विद्युत धारा प्रवाहित होती है और प्रतिरोध के कारण गर्मी उत्पन्न होती है।
रोजमर्रा की जिंदगी में इसके प्रयोग:
विद्युत हीटर – कमरे को गर्म करने के लिए विद्युत ऊर्जा को ऊष्मा में बदलता है।
विद्युत इस्त्री – कपड़ों को प्रेस करने के लिए गर्म होता है।
फ्यूज – जब धारा सीमा से अधिक हो, तो यह पिघलकर सर्किट की सुरक्षा करता है।
अन्य विकल्प:
LED और टॉर्च – प्रकाश उत्पन्न करते हैं, ऊष्मा नहीं।
विद्युत पंखा और मोटर – विद्युत ऊर्जा को यांत्रिक ऊर्जा में बदलते हैं।
विद्युत घंटी और बजर – ध्वनि उत्पन्न करते हैं, ऊष्मा नहीं।
⭐ Extra Facts / अतिरिक्त तथ्य:
The heating effect is directly proportional to the square of current (I²R law).
It is used in devices designed to produce heat intentionally.
