A resistance of 100 ohms and inductance of 0.5 henries are connected in series With a battery of 20 volts. Find the current at any instant if the relation between L,R,E is L `(di)/(dt)+Ri=E.`
Solution is given by ,
At t = 0, i = 0 `thereforec=E/R`
`therefore "i" = E/R(1-e^(-(Rt)/L))`
For given condition R = 100, L = 0.5, E = 20
