In this case, 24 simultaneous calls can be put through switch. Generally a 24-outlet Uni-selector is used as a selector hunter. Every one of the 24 outlets is connected to one two-motion selector. So a subscriber has access to all the 24 two-motion selectors in system. Corresponding outlets of all the selector hunters are commoned and hence all subscribers have access to all the two-motion selectors. This scheme is displayed in Figure. Call establishment in this scheme takes place in two steps. Firstly, when subscriber lifts his receiver handset, his Uni-selector hunts through contact positions and seizes a free two-motion selector. At the subsequent step, two-motion selector responds to dial pulses for appropriate connection.
Q. Consider an RL series circuit excited by (a) v(t) = 20e -2t V, and (b) v(t) = 20 V. Determine the forced component of the voltage across the inductor for R = 2 and L = 2H.
