अवधारणा :

  • जब भी कोई धारा प्रतिरोध में प्रवाहित होती है तब उसमें ऊष्मा उत्पन्न होती है
  • विद्युत धारा द्वारा ऊष्मा उत्पन्न करने की घटना को विद्युत धारा का तापन प्रभाव कहा जाता है।
  • जूल में उत्पादित ऊष्मा (H) की मात्रा =I2R
  • लेकिन हम जानते हैं कि, V = IR
  • इसलिए, उत्पादित ऊष्मा की मात्रा (H) जूल में = I2R= VIt

जहां I = धारा, R = प्रतिरोध, t = लिया गया समय और V = विद्युत विभव

व्याख्या:

दिया गया - I = 2 A, V = 24 V और t = 5 मिनट = 5 × 60 सेकंड = 300 सेकंड

  • जूल में ऊष्मा का उत्पादन (H) निम्न है

⇒ H = VIt

⇒ H = 24 × 2 × 300 = 14400 J
