4- The switch has been at position a for a long time. If it moves from position a to position b at t = 0, calculate v(t) and Vr(t) for t > 0. 12 V 192 ww 292 www -19 a 2.5 H b m t=0 +51 10 Q2 - VR 10 V

Do it accurate correct

If the values of V(t)and I(t) differ by 0° how does that affect the calculations used to find ZL

2. The switches in the circuit below change at time equal zero as indicated in the figure. Find vo(t) for t> 0+ 15V + 120 m ix 1402 m Xt=0 ww 170 50mH m 120 + Vo 170
