3.	2 kW शक्ति अनुमतांक का एक विद्युत तंदूर किसी घरेलू विद्युत परिपथ (220 V) में प्रचालित किया जाता है जिसका विद्युत धारा अनुमतांक 5 । है, इससे आप किस परिणाम की अपेक्षा करते हैं? स्पष्ट कीजिए।
Answer» विद्युत तंदूर की शक्ति (P) = 2 kW = 2000 W अत: विद्युत तंदूर द्वारा ली गई धारा (I) = P/V = 2000/220 = 9 A (लगभग) जबकि विद्युत परिपथ का विद्युत धारा अनुमतांक 5 A है और तंदूर 9 A की दर से धारा लेता है, इसलिए यह परिपथ अतिउष्मता अथवा अतिभारण के कारण टूट जायेगा \|

2 kW शक्ति अनुमतांक का एक विद्युत तंदूर किसी घरेलू विद्युत परिपथ (220 V) में प्रचालित किया जाता है जिसका विद्युत धारा अनुमतांक 5 । है, इससे आप किस परिणाम की अपेक्षा करते हैं? स्पष्ट कीजिए।

Answer»

विद्युत तंदूर की शक्ति (P) = 2 kW = 2000 W

अत: विद्युत तंदूर द्वारा ली गई धारा (I) = P/V

= 2000/220 = 9 A (लगभग)

जबकि विद्युत परिपथ का विद्युत धारा अनुमतांक 5 A है और तंदूर 9 A की दर से धारा लेता है, इसलिए यह परिपथ अतिउष्मता अथवा अतिभारण के कारण टूट जायेगा |
