Question: An inductor has a current I(t) = (0.500 A) cos[(275 s)t] flowing through it. If the maximum emf across the inductor is equal to 0.500

An inductor has a current I(t) = (0.500 A) cos[(275 s")t] flowing through it. If the maximum emf across the inductor is equal to 0.500 V, what is the self-inductance of the inductor? O 4.37 mH O 2.75 mH O 1.43 mH O 3.64 mH O 0.73 mHA series LR circuit consists of a 2.0-H inductor with negligible internal resistance, a 100-ohm resistor, an open switch, and a 9.0-V ideal power source. After the switch is closed, what is the maximum power delivered by the power supply? O 0.090 W O 0.40 W O 81 W O 8.1 W O 0.81 W
