Question
The power dissipated in a conductor of resistivity ρ connected across a battery is directly proportional to Only one correct answerA.ρ2B.√ρρC.ρD.ρ–1
Solution
The power (P) dissipated in a conductor can be calculated using the formula P = I^2 * R, where I is the current and R is the resistance.
The resistance (R) of a conductor can be calculated using the formula R = ρ * L / A, where ρ is the resistivity, L is the length of the conductor, and A is the cross-sectional area of the conductor.
Substituting the second equation into the first, we get P = I^2 * (ρ * L / A).
From this equation, we can see that the power dissipated in a conductor is directly proportional to the resistivity (ρ).
Therefore, the correct answer is C. ρ.
