JEE Main & Advanced Physics Current Electricity, Charging & Discharging Of Capacitors / वर्तमान बिजली, चार्ज और कैपेसिटर का निर JEE PYQ-Current Electricity Charging and Discharging of Capacitors

  • question_answer
    The temperature dependence of resistances of Cu and un doped Si in the temperature range 300-400K, is best described by :-            [JEE MAIN - I 3-4-2016]

    A) Linear decrease for Cu, linear decrease for Si.

    B) Linear increase for Cu, linear increase for Si.

    C) Linear increase for Cu, exponential increase for Si

    D) Linear increase for Cu, exponential de crease for Si

    Correct Answer: D

    Solution :

    [d] Factual Cu is conductor so with increase in temperature, resistance will increase Si is semiconductor so with increase in temperature resistance will decrease
