Retracing the steps which led to formulate the hypothesis on electromagnetic nature of light, two circuits (RL, RC) in alternating current regimen were observed to measure the constants of vacuum permeability and permittivity, yielding $\mu_{0}=(1.27\pm 0.51)\cdot 10^{-6} H/m, \varepsilon_0=(6.1\pm 2.2)\cdot 10^{-12} F/m$. Moreover, the speed of light was evaluated as $c=(3.6\pm 1.4)\cdot 10^{8}$ m/s, near the accepted value $2.99\cdot 10^{8}$ m/s.
