Simulate circuits in your web-browser at: http://androidcircuitsolver.com/app.html

As I approached my
senior year for my B.S. in Electrical Engineering, I wanted to create

something that most people hadn't created
before, a circuit simulator! It was about the

experience, the learning, and the the journey itself. I put together
this application to

package my knowledge in Electrical Engineering to some day help another student have

an
easier time in their scholastic pursuits and in turn teach them about circuits.

Circuit Solver is far from perfect
and there are lots of things that could be optimized.

It will however, simulate a majority of linear Circuits and a
decent amount of smaller

scale Non-Linear Circuits. If this app helps you in any way, i'd appreciate you spreading

the word to help support my efforts, Thanks!

Think of Circuit Solver as an electronic circuit board, you drag
your electrical components

and place them on one at a time. You hook up some sources and you place some meters

to read the values. If you need to analyze the waveform, grab some electrical leads and

view them with an
oscilloscope. There are many SPICE tools out there for PC such as

Multisim, LTSpice, and PSpice. Circuit Solver
doesn't compare to their raw power

but it is optimized to run on mobile devices which makes it both portable and
easily

accessible to anyone in need of circuit solutions. Circuit Solver strives to verify Ohm's law,

Kirchhoff's current and voltage laws by creating models that are both stable and efficient.

Make circuit solver
your first step in circuit design!

DC Simulation:

To simulate 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.

Transient Simulation:

In transient simulation
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
Backward Euler method.

Non Linear Simulation:

Non linear simulation 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.

Built-in-Oscilloscope:

Visualize waveforms through the use of the built in oscilloscope. To use
this feature

simply link either a volt meter or an amp meter to the graph by tapping on them and

pressing the
eye, in order to view the wave.

Saving Schematics/Circuits:

Save your circuits on your device to use anywhere
you go and at any time. You may

also capture screen shots of the circuits you build. These screen shots are saved

locally on your device.
