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) 5 d dt (4 sin 2 ) (4 sin 2 ) t t. 5 (8 cos 2 ) (4 sin 2 ) t t. 80 [2 cos 2 sin 2 ] t t. 80 [sin(2 2 ) t t sin(2 2 )] t t. [cos 4 | ] 20 (1 cos 4 ) t t. P 2 determine the value of the inductance l in the circuit shown in figure p 2, given that leq = 18 h.
