Download Solution PDFसंकल्पना:
विद्युत शक्ती: ज्या दराने विद्युत ऊर्जेचे उर्जेच्या इतर प्रकारांमध्ये अपघटन होते त्यास विद्युत शक्ती
म्हणतात, म्हणजे;
\(P = \frac{W}{t} = VI = {I^2}R = \frac{{{V^2}}}{R}\)
जेथे V = विभवांतर, R = रोध आणि I = विद्युत धारा.
गणना:
दिलेल्याप्रमाणे - विभवांतर (V) = 200 V आणि विद्युत धारा (I) = 0.5 A
- विद्युत शक्ती खालील स्वरूपात लिहिली जाऊ शकते,
⇒ P = VI
⇒ P = 200 x 0.5 = 100 W
