NV7009 RLC Resonance Trainer is very exclusive product provides complete learning content for both series and parallel resonance. Resonance is an interesting phenomenon in electrical circuits in which inductive and capacitive elements behave to make a zero impedance circuit. This explanation is given with the help of passive circuits on the trainer. Multiple combination of components has been provided so that students can calculate resonance frequencies for these different combinations. Concept of Resonance frequency is explained very clearly which can be easily elaborated either on Oscilloscope or by on board display.
