MODELLING IN THE PACKET OF MATHCAD OF TRANSITION PROCESSES IN RESISTIVE-CAPACITIVE CIRCUITS IN CASE OF DC SUPPLY VOLTAGE AND DISCRETE CHANGE OF PARAMETERS OF ELEMENTS

The mathematical model of transitional processes in electrical circuits with storage of electric energy in case of constant power voltage realized in MathCad packet is offered. The solution of differential equations in the form of Cauchy by the Runge-Kutta method is considered. The methods allowing to avoid errors in case of spasmodic changes of resistance of charge resistor or capacity of electrical condenser are offered.
