What is meant by Resonance what are the different types of
resonance and what are uses of them?

Answer Posted / sanjeev kumar

XL=2Ï€fl
XC=1/2Ï€fc
if XL=XC
then2Ï€fl=1/2Ï€fc
this is the condition of resonance

due to resonance the current flowing in the circuit is very high due to high current risk damege of equipment.
for the protection of the resonance we use reactor for the protection . it works as a low pass filter . Only pass up to the fifth harmonic of the resonance.
