Q21. A cylindrical conductor of length l and cross-section area A is connected to a DC source. Under the influence of electric field set up due to source, the free electrons begin to drift in the opposite direction of the electric field. (I) Draw the curve showing the dependency of drift velocity on relaxation time. (II) If the DC source is replaced by a source whose current changes its magnitude with time such that I = Io sin 2πνt , where ν is the frequency of variation of current, then determine the average drift velocity of the free electrons over one complete cycle. |CBSE SAMPLE PAPER 2025| 2025 CBSE SAMPLE PAPER:    • 2025 CBSE SAMPLE PAPER   This video is helpful for students preparing for Jee & neet Aspirants and Cbse & state board students ‎‪@physicswithrishirajsir‬   _______________________________________________ Ncert Examples Class 12th:    • Ncert Examples Class 12th   Ray Optics:    • 9. Ray Optics and optical instruments   Electrostatic and Field:    • 1-Electric Charges and field   Electrostatic potential and capacitance:    • 2.Electrostatic potential and capacitance   Moving charges and magnetism:    • 4.Moving charges and magnetism   Simple Harmonic Motion:    • Simple Harmonic Motion   _______________________________________________ #jeemains #jeeadvanced #cbseboard #ncert ‎‪@physicswithrishirajsir‬
