Document Summary

Problem set #7 (total 4 problems: 5 pts each) P 1 the current, i(t), in a 5-h inductor is i t. 0 where the units of time are s and the units of current are a. Determine the power, p(t), absorbed by the inductor and the energy, w(t), stored in the inductor. Hint: 2 (cos a)(sin b) = sin (a + b) + sin (a b) P 2 determine the value of the inductance l in the circuit shown in figure p 2, given that leq = 18 h. P 3 the switch in figure p 3 has been open for a long time before closing at time t = 0. Find vc(0+) and il(0+), the values of the capacitor voltage and inductor current immediately after the switch closes. Let vc( ) and il( ) denote the values of the capacitor voltage and inductor current after the switch has been closed for a long time.
