  1. Question 1

    Electromagnetic Induction. Asked once: 27 Jan 2024

    23
    Two coils have mutual inductance 0.002H0.002H. The current changes in the first coil according to the relation i=i0i =i_{0} sin ωt\omega t, where i0=5 Ai_{0}= 5\text{ }A and ω=50π\omega= 50\pi rad/srad/s. The maximum value of emf in the second coil is παV\frac{\pi}{\alpha}V. The value of α\alpha is ____ .
  2. Question 2

    Electromagnetic Waves. Asked once: 27 Jun 2022

    105
    Given below are two statements: Statement I: A time varying electric field is a source of changing magnetic field and vice-versa. Thus a disturbance in electric or magnetic field creates EM waves. Statement II: In a material medium. The EM wave travels with speed v=1μ0ε0v =\frac{1}{\sqrt{\mu_{0}\varepsilon_{0}}}. In the light of the above statements, choose the correct answer from the options given below:
