1.	Barretter B is a conductor whose idealized characteristic. The barretter is connected in series with a resistor of resistance R to a power supply of e.m.f. epsi. Find the current in the circuit and the voltage drop across the barretter and the resistor. Neglect the internal resistance of the power supply.
Answer» Solution :The current in a circuit containing a barretler is determined hy the transconductance of the DEVICE and is independent of the circuit.s resistance. However, current flows only if `epsi-i_(0)R gt 0. i.e, epsi gt i_(0)R`. OTHERWISE the voltage ACROSS the horretter DROPS to zero, and the current through it ceases to flow.

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 ?
