- विद्युत परिपथामध्ये विद्युतरोध जोडल्यास विद्युतधारेने त्यात उष्णता निर्माण होते, यास विद्युतधारेचा औष्णिक परिणाम असे म्हणतात.
- हस्तांतरित होणाऱ्या उष्णतेचे प्रमाण ज्युलमध्ये (H) = I2Rt = VIt
- येथे, I = विद्युतधारा, R = रोध, t = वेळ व V = विभवांतर
स्पष्टीकरण:
दिलेले आहे - I = 2 A, V = 24 V व t = 5 मिनिटे = 5 x 60 सेकंद = 300 सेकंद
- हस्तांतरित होणाऱ्या उष्णतेचे प्रमाण ज्युलमध्ये (H)
⇒ H = VIt
⇒ H = 24 x 2 x 300 = 14400 जूल
