Detailed Solution
Download Solution PDFसंकल्पना:
- ओहमचा नियम: स्थिर तापमानात, विद्युतप्रवाह वाहून नेणाऱ्या वायरमधील विभवांतर हे त्यामधून वाहणाऱ्या विद्युतप्रवाहाच्या थेट प्रमाणात असते.
म्हणजे V = IR
जेथे V = विभवांतर, R = रोध आणि I = विद्युतप्रवाह.
स्पष्टीकरण:
दिलेल्याप्रमाणे - V = 6 V आणि I = 0.4 A
- ओहमच्या नियमानुसार, V = IR
- वरील समीकरण रोधासाठी असे लिहिले जाऊ शकते
\(\Rightarrow R = \frac{V}{I}=\frac{6}{0.4\times 10^{-3}}=15\times 10^{3}\, \Omega=15\, k\Omega\)
