If a conductor has a potential
If a conductor has a potential difference of 1 volt across its ends and a current of 1 ampere flows through it, what is its resistance?
यदि किसी चालक के सिरों पर विभवांतर 1 वोल्ट है और उसमें से 1 ऐम्पियर की धारा प्रवाहित होती है, तो उसका प्रतिरोध क्या होगा?
Detailed Solution & Logic
1 ohm/ 1 ओम
⚡ Explanation
We use Ohm’s Law, which states:
V=IR
Where:
V = Potential difference (Voltage)
I = Current
R = Resistance
$V = 1 \ \text{volt}$
$I = 1 \ \text{ampere}$
Ohm’s Law:
$V = IR$
Resistance,
$R = \dfrac{V}{I}$
$R = \dfrac{1}{1}$
$R = 1 \ \Omega$
Extra Facts:
One ohm is the resistance when 1 volt produces 1 ampere current.
Resistance depends on length, area, and material of the conductor.
Metals like copper have low resistance, while nichrome has high resistance.
⚡ व्याख्या
हम ओम का नियम (Ohm’s Law) प्रयोग करते हैं:
अतिरिक्त तथ्य:
जब 1 वोल्ट विभवांतर से 1 ऐम्पियर धारा प्रवाहित होती है, तब प्रतिरोध 1 ओम होता है।
प्रतिरोध चालक की लंबाई, क्षेत्रफल और पदार्थ पर निर्भर करता है।
तांबा (Copper) कम प्रतिरोध वाला तथा नाइक्रोम (Nichrome) अधिक प्रतिरोध वाला पदार्थ है।
👉 Therefore, the correct option is 1 ohm / 1 ओम.
