SF Physics Experiments

RLC circuit has a very important feature, that is, the produced amplitudes of circuit-current will closely depend on the input frequency. Generally speaking, partial signal will be filtered, but partial might be augmented as several power sources with different frequency, in the circuit, are delivered simultaneously. Here amplified signal of frequency is primarily determined by the value of L and C selected. However the converse effect will appear as the higher resistance R is involved. Thus the so called "filter effect" might be taken as an important characteristic in RLC circuit. In addition, RC circuit, in the absence of power supplier, is usually performed as a convertor of electric energy in the envelope of electric field. Here the electric energy charged into or discharged from capacitor C is based on the demand of current flow in circuit. That might be also used as "Quick Battery" existing in almost all electronic circuits.
