Question 3

Two semi-infinite dielectric regions separated by a plane boundary at y = 0. The dielectric constant of region 1(y < 0) and region 2 (y > 0) are 2 and 5, respectively. Region 1 has uniform electric field , where and are unit vectors along the x, y and z axes, respectively. The electric field in region 2 is

Question 4

Consider a one-turn rectangular loop of wire placed in a uniform magnetic field as shown in the figure. The plane of the loop is perpendicular to the field lines. The resistance of the loop is 0.4Ω, and its inductance is negligible. The magnetic flux density (in Tesla) is a function of time and is given by B(t) = 0.25 sin ωt, where ω= 2π × 50 radian/second. The power absorbed (in watt) by the loop from the magnetic field is ______.

Question 5

Two magnetically uncoupled inductive coils have Q factors q1 and q2 at the chosen operating frequency. Their respective resistances are R1 and R2. When connected in series, their effective Q factor at the same operating frequency is
