1. (See attachment) Q1 a, Determine I1,I2and I3 after 5 time constants
b, when the switch is first closed ie t=0
c,when the switch re opens
2. I total=I1(i1+I2)
i=I[1e ^{RL/L}
3. i havnt practiced any circuits with resitance in series and parallel just looking for a way forwerd on how to write the equations down for each one
with the circuit initially closed i imagine its basic kirchoffs laws to calculate I1,2 and 3 but these will be very small as almost all of the supply voltage is going to the inductor but after 5 time constants at 63.2% steady state the current values will increase
any help appreciated
regards Ian
