Question: Solve Prob. 19 when the EMF (electromotive force) is acting from 0 to only. Can you do this just by looking at Prob. 19, practically
Data from Prob. 19
Using Laplace transforms, find the currents i1(t) and i2(t) in Fig. 148, where v(t) = 390 cos t and i1(0) = 0, i2(0) = 0. How soon will the currents practically reach their steady state?

80 82 v(t) ll 2H 4 H Network i(t) -i;(t) 40 -ig(t) 20 4. 10 -20 -40 Currents 6.
