It is the modification of the ENERGY IN RLC experiment, where the phase relations for individual components, i.e. resistor R, inductor L and capacitor C may be studied with respect of the frequency. Remote experiment may be used both as laboratory experiment and for the project and homework.

The electrochemical sources of electric energy are important components for various appliances. Two basic parameters of any DC electromotive voltage source are important – the electromotive voltage and the internal resistance of the source.

Frequency dependent phenomena in RLC circuits are basis for both demonstration of phenomena in electricity and electromagnetism and for circuits with resonance phenomena. Usually, the voltage transfer and phase characteristics (i.e.
