1. electrical resonance is a state when inductive effect of a circuit is nullified by the capacitive effect and the circuit, then, behaves as a pure resistance.
2.This happens because inductance and capacitance have opposite properties - while inductive reactance increases with frequency, capacitive reactance decreases with frequency.
LC circuit
impedence
Z=0
Or Z=infinite
In a simple series LC circuit
resonance occurs
when
inductive reactance= capacitive reactance
giving zero impedance and infinite current.
