About Circuit Solver

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, OrCAD, 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.

W70%
by W####:

Honestly it is very practical it deserves higher rating

X70%
by X####:

Terrible user interface.

M70%
by M####:

(revised review) Great and accurate simulator offering more in free version than any other app. Easy to use with solid intro documentation. Thanks to the author who listens about new ideas and suggestions, and trying to implement them.

X70%
by X####:

Its ok if you block the logic gates in the lite version but limiting to 2 components of each type makes the app totally worthless and useless for any kind of test that requires a simulation

J70%
by J####:

Crash the app frequently

X70%
by X####:

A Circuit solver with no circuits to solve. I thought it would be some cool technician game were you had a goal to fix the circuit to get a desired output. But for a "circuit solver" there isn't anything to solve or any goals at least in the game. Its just your average circuit sim... Nothing special... I mean I wouldn't publish a game called "dragon hunter" and not have you hunt dragons... Or a car racing game without the racing. Or zombie shooter without the shooting. Or a flight sim without the flying.

Is there no way to use it without being taken to the net? In my opinion if you can't accomplish the goal of the app download with out the interference factors why bother?

Excelente aplicación, básica pero ayuda bastante. Solo me gustaría que agregaran más slots para guardar proyectos para no tener que eliminar alguno de los que ya estaban.

E70%
by E####:

Please add many more components, such as speaker, oscillator, and everything about audio circuit. By the way, there is bug when after I minimize tab and reopen it, the screen totally blank (does not appear anything). And please make the bigger space. (I need much more space to draw.)

Bro plz add the more ekupe. Ment plz

D70%
by D####:

Good app for small circuits.

X70%
by X####:

Limited number of components, a lot of circuits are not able to be simulated

R70%
by R####:

The interface let's it down even getting back the examples is a pain. Its a great app though.

E70%
by E####:

Please add more components like SCR

add more components

Bulshit

Love the app it works good. Just wish they had some ic's, like at least 555 timer.

Get a life....buddy,,,

T70%
by T####:

It's a good app but there is a mistake that when I create a transistor oscillator I will not work properly in this app

X70%

Add SCR pls

X70%

giving totally wrong values from practical

Superbbbb....really coooool!!!!

F70%

Would me more glad if input can be set by us mathematically like ( A + m(t)) cos wt. Thanks.

I70%
by I####:

Many pros, only a few cons. I would be very greatful if there where an option to alter the properties of the LEDs.

Great

X70%
by X####:

Nice app.Works fluently.Some minor errors in ammeter readings but otherwise a perfect app!

J70%
by J####:

Simple and easy to use but please add ability to comment on the circuit and some important components like zener diode are missing.

P70%
by P####:

Did what I needed it to do

Q70%
by Q####:

Horrible, glitchy application being promoted with YouTube spam. Multiple fake Google accounts are being used to give 5 star ratings. Do yourself a favor and get yourself a real simulator not this travesty of an app.

Nice user interface and works nicely!

Q70%
by Q####:

Since it' still new there isn't that much stuff, the UI is kind of hard to use but I found some help on your website.

F70%
by F####:

I love it! Its so simple but still I can't get enough of it! Its awesome!

Q70%
by Q####:

Haha, this is gonna make my homework a heck of a lot easier!

P70%
by P####:

I can't wait to test out my circuits here first!

M70%
by M####:

I saw my friend using this app and now i'm hooked!

Q70%
by Q####:

It's a smooth application but add an oscilloscope so I can read values.
