Question 10.Current in an electric circuit is described by the differential equation LdI + RI = E ,dtwhere L, R and E are positive constants. At the moment t = 0 there is no current: I = 0. Solve the differential equation to find I(t) in terms of the constants and sketch the solution indicating coordinates that you think are important. What will be the practical value of the current after a very long time?
