1.	In a transformer primary has 50 turns and secondary has 10 turns . The RMS voltage in the primary is 120V . Find the RMS secondary voltage in the open circuit .if the secondary has a load of 12 Omega . What are the currents in the primary and secondary ?
Answer» SOLUTION :`V_S/V_P= N_S/N_P = I_P/I_S` `N_P = 500 , N_S = 10 , V_P = 120 V` ` therefore V_S = N_S/N_P XX V_P = 10/500 xx 120= 2.4 V` by the ohm.s law current in the SECONDARY `I_S = V_S/R_S = (2.4)/(12) = 0.2A` Hence current in the primary `I_P = N_S/N_P xx I_S = 10/500 xx 0.2 = 4 xx 10^(-3) A ` `I_P = 4mA`

A wire is bent to form a semicircle of the radius a. The wire rotates about its one end with angular velocity omega . Axis of rotation is perpendicular to the plane of the semicircle . In the space , a uniform magnetic field of induction B exists along the aixs of rotation as shown in the figure . Then -
A massless non conducting rod AB of length 2l is placed in uniform time varying magnetic field confined in a cylindrical region of radius (R gt l) as shown in the figure. The center of the rod coincides with the centre of the cylin- drical region. The rod can freely rotate in the plane of the Figure about an axis coinciding with the axis of the cylinder. Two particles, each of mass m and charge q are attached to the ends A and B of the rod. The time varying magnetic field in this cylindrical region is given by B = B_(0) [1-(t)/(2)] where B_(0) is a constant. The field is switched on at time t = 0. Consider B_(0) = 100T, l = 4 cm(q)/(m) = (4pi)/(100) C//kg. Calculate the time in which the rod will reach position CD shown in the figure for th first time. Will end A be at C or D at this instant ?
