The article proposes the formula which has been proved and then called the initial universal formula. This formula permits to find the solution either for voltage or electric current in any linear electrical circuit by means of using the finite conditions of elements, i.e. short circuit or open circuit resistances (conductances). The article also presents the method of transforming the initial electric circuit into a great number of finite electrical circuits having only the sources and passive elements in the finite conditions. That method allows one to pass from the initial universal formula to the finite universal formula. The formula permits to find voltage or current in any section of an initial electrical circuit. Thus the calculation of voltage and current values in a circuit needs only the formal procedure of transforming the initial electrical circuit and does not need any equations and their solutions.
