Circuit Solver Pro [for Android]

DC Analysis:
To solve the circuits, a matrix is defined based on all the components inside the circuit. The application solves the circuit using matrix manipulations such as LU-Decomposition and matrix inversion. DC Analysis is completed by writing a series of nodal equations. The equations are solved simultaneously to obtain a unique solution.

AC Analysis:
AC Analysis occurs after the transients in the system have decayed. This is usually after five time constants of the circuit of interest.

Transient Analysis:
In transient analysis we use numerical integration to determine the response of RLC circuits. Numerical integration allows for one to solve for discrete moments of time and in effect integrate their response. This application only supports the Trapezoidal method.

Non Linear Analysis:
Non linear analysis is used for components such as diodes, LEDs, and transistors. The solver first guesses the approximate value of the solution and is refined through the use of a Newton-Raphson process. It utilizes linear approximation to predict the answer through successive iterations.
