Question

ਕਿਸੇ ਦੋ ਚਾਲਕਾਂ Aਅਤੇ B ਦੇ ਸਿਰਿਆਂ ਵਿਚਕਾਰ ਪੁਟੈਂਸ਼ਲ ਅੰਤਰ ਅਤੇ ਬਿਜਲੀ ਧਾਰਾ ਦੇ ਵਿਚਕਾਰ ਗ੍ਰਾਫ ਖਿੱਚਿਆ ਗਿਆ ਹੈ, ਚਿੱਤਰ ਵਿੱਚ ਦਰਸਾਏ ਅਨੁਸਾਰ ਕਿਹੜੇ ਚਾਲਕ ਦਾ ਪ੍ਰਤੀਰੋਧ ਜ਼ਿਆਦਾ ਹੈ- Graph between electric current and potential difference across two conductors A and B is plotted as shown in figure. Which of the two conductors has more resistance? ​

Answer 1

Answer:

Conductor A

Explanation:

Conductor A has more resistance

Answer 2

OPTION (B) IS CORRECT.

B) CONDUCTOR B

Explanation:

• Ohm's law states that the potential difference is directly proportional to current.
• It can be represented as V=IR. So, R=V/I.
• If we will fix the voltage, then the current flowing through conductor B is greater than conductor A. As, R ∝ 1/I.
• Therefore, resistance of A will be greater than B.
• Option (B) is correct.

        $R\alpha \frac{1}{I} \\\\I_{B} > I_{A}\\\\R_{B} < R_{A}$
