At resonance the circuit is purely resistive.

In parallel resonance voltage is maximum.

In parallel resonance resistance is maximum as the "Parallel LC tank circuit" acts like an open circuit.

In series RLC.

R=min.
I=max.

In parallel RLC.

Y=min => R=Max.
I=min.

In parallel resonance circuit, the circuit is purely resistive. Hence, the circuit depends on the Voltage source & and Resister.

By Ohms Law, V is directly proportional to the current (I).

At Resonance, the voltage is maximum.

Hence, the current flowing circuit at resonance is MINIMUM.

In parallel resonance voltage is maximum and current is minimum.

Can anybody explain what is resonance?

Zin=R -----> maximum.
I|w=w0=Vs/R------> minimum.

In parallel circuits, the voltage (V) is the same, but there's current division in such circuit as such current is minimum.

According to Ohm's law V=IR which seems to be a linear relationship.

How can current be minimum when the voltage is maximum?

Resonant circuit means at low impedance an inductor is in series with the capacitor, low impedance meance current flow maximum but when in a parallel circuit vice versa voltge minimum.

In parallel resonace circuit voltage is maximum and current is mininum.
