Q2. The capacitor in the Fig. Q2 is initially charged to 25V. the switch is moved to position 1. 5s later, it is moved to position 2 and keep it to another Js. Deter..ine. (a) the time constant of the charging circuit; ( b ) the duration of the transient, the expression for V and ic in position 1; (d) the valle or @ and i in position 1 att 1s the expression for V. and ir- in position 2. the value or i at the instant in position 2.
