worm The form legs the current waveform The two waveforms are from Seperate routs The voltage and the current waveforms are in phase with each other QUESTION 3 400 40 The above elements represent Infinite admittance Infinite impedance Pure resistance Zero impedance QUESTION 4 Chek Sun and end uit Chick Se Allers

Answer 1

Option B IS CORRECT.

Since,here we can see this is parallel LC circuit with XL= Xc = 40 ohm. And hence this is in resonance. Admittance of parallel LC circuit is minimum at resonance. So if admittance is minimum then impedance will be maximum.

So impedance will be infinity.(Max) Option B is correct.

Note: impedance and admittance at reciprocal of each other. There is admittance is minimum then impedance wil be maximum and vice versa.
