Figure P7.330 Ωwat=0+60 V+702V2-90 Ωw0.32 HV1 73 In the circuit shown in Fig. P7.3, the switch makescontact with position b just before breaking contactwith position a. As already mentioned, this isknown as a make-before-break switch and isdesigned so that the switch does not interrupt thecurrent in an inductive circuit. The interval of timebetween "making" and "breaking" is assumed to benegligible. The switch has been in the a position fora long time. At t = 0 the switch is thrown from posi-tion a to position b.a) Determine the initial current in the inductor.b) Determine the time constant of the circuitfort > 0.c) Find i, v₁, and v₂ for t≥ 0.d) What percentage of the initial energy stored inthe inductor is dissipated in the 90 resistor1 ms after the switch is thrown from position a toposition b?
