The paper deals with vector Ito stochastic integral equations. We replace a parameter in the deterministic model of the RLC electrical circuit with a stochastic one, by adding a noise term to the coefficient and so we introduce the stochastic model of the circuit as a second order stochastic differential equation. By the Ito calculus we solve this equation. For numerical simulations of the stochastic trajectories we present the Euler and the Milstein numerical schemes. We used Matlab for the computations of the stochastic trajectories in the examples.
