Answer / archana

An electrical circuit consisting of various active and
passive sources,in such a circuit,the state in which the
current is maximum is called RESONANCE.
So the network should be purely resistive,for that the
inductive reactance and the capacitive reactance should be
equal.then Vl and Vc will be equal and they cancel
eachother as they both are 180 degrees out of phase.....

Answer / gowri sankararao . a

In electrical circuit if the resistance offered by iductor
is exactly equal to the resistance offered by the capacitor
then there is formation of resonance .

>>>At resonance power factor offerd by the network is UNITY

types of resonance :
there are two types of resonance .those are

1. series resonance

2. parallel resonance

Answer / jeyapandian

in resonance XL = Xc
two type:
series - current is min.Z in max.
parallel- vice versa
and the P.f = 1 bcz R=Z

In a d.c circuit, if current and resistance are known, power (P=I*I*R) can be determined. This relationship also applied to an a.c circuit. Comment the reason for this.
