A wire of copper having length I and area of cross-section A is taken and a current I is flown through it. The power dissipated in the wire is P. If we take an aluminum wire having same dimensions and pass the same current through it, the power dissipated will be
  • a)
    P
  • b)
    < P
  • c)
    > P
  • d)
    2P
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
A wire of copper having length I and area of cross-section A is taken ...
  • A wire of copper having length I and area of cross-section A is taken and a current I is flown through it. The power dissipated in the wire is P. If we take an aluminum wire having same dimensions and pass the same current through it, the power dissipated will be > P.
  • Aluminum has higher resistance as compared to Copper for same length, current flown through it, and power dissipated is directly proportional to resistance, so power dissipated will be > P.
