Linear oscillatory systems

Tesla transformer combined mode calculation. Charge Pump

The combination of two modes of operation of the Tesla transformer coil increases the efficiency of its work, and allows it to work as a pump of charges from the Earth. This calculator is dedicated to the search for optimal parameters for such modes, efficiency and power resulting from such work.

Calculation of a series RC or RL circuit

The calculator calculates the output parameters: operating voltage, power dissipation and voltage phase, depending on the input sinusoidal voltage for RC or RL circuit. The value of reactance - capacitor or inductance - is also calculated for a given frequency.

Energy balance between power supply and capacitor

The calculator is designed to calculate the energy balance of the power source and the charged capacitor through the converter circuit, which is a "black box", about the structure of which we know nothing. But we know the data of the power supply, the data of the capacitor and the charging time. Based on these data, we calculate the energy expended by the power source for the operation of the converter, and the energy received on the capacitor after charging is completed. By dividing the energy expended and received, we get their balance

Online Circuit Simulator

The simulator allows you to visualize some of the processes that occur in electronic circuits. The program is distributed under a free license as an educational one. It is not recommended to use the program to simulate real circuits, since many components in it are idealized. The following languages are supported: English, Russian, Danish, German and Polish.
