DE which is the differential equation represents the LRC series circuit where

L d²q/dt² + Rdq/dt + I/Cq = E (t) = 150V.

Initial condition is q (t) = 0 and i (0) = 0.

To find the charge q (t) by using Laplace transformation by

Substituting known values for DE

L*d²q/dt² + 20 * dq/dt + 1/0.005 * q = 150

d²q/dt² + 20dq/dt + 200q = 150
