Question : 136 of 200

Marks: +1, -0

What is the value of the total impedance (in ohms) of a tank circuit working at resonant frequency having a capacitance of 0.01 mF and an inductance of 0.01 mH?

Validate

Solution:

at Resonance

X_L = X_C

Z = J X_L∥- J X _ C

={J X_L(- J X _ C)}/{ J X _L- J X _ C}

Z=∞

So tank circuit is open circuit at Resonance.
