Solving Ohms law for DC (E=I*R) is straight forward but what about AC. For AC (E=I*Z) looks simple but the value Z is composed of an inductor (a coil of wire) and a Capacitor. The AC frequency affects these calculations in a somewhat complex manner. This program makes calculating easy. Like my...
Solving Operational Amplifiers is straightforward but can become complicated without much effort. This simulator is designed to help simplify your calculations in an easy to use format. Many times you may not know exactly how to design a circuit. Our program starts with a design using an AC Input...
Historically spring design has always been a challenge. In a manufacturing environment the use of stock springs has always been the first approach. But then the design changes a little or the stock spring is not quite what is needed and the designer must resort to designing a spring modification...
This software is used to reduce the risk of damaging the hardware due to faulty design of the circuit. It helps the designer of the circuit, to build and test the cirucit in software, before trying it out in hardware.If anything is found wrong with the design,it can be detected and debugged at...
