In an RL series circuit with L = 1/100 H, R = 20 Ω, and E = 60 V. Determine the limit of the maximum current reached (At the function you found to determine the current as a function of time apply the limit when t goes to infinity) and determine the time in which it reaches half of that value. Take i (0) = 0 A.

A sealed vertical cylinder of radius R and height h = 0.616 m is initially filled halfway with water, and the upper half is filled with air. The air is initially at standard atmospheric pressure, p0 = 1.01·105 Pa. A small valve at the bottom of the cylinder is opened, and water flows out of the cylinder until the reduced pressure of the air in the upper part of the cylinder prevents any further water from escaping. By what distance...
