Question

DRAW THE PLOT SHOWING THE VARIATION OF THE CURRENT I AS A FUNCTION OF ANGULAR FREQUENCY w OF THE APPLIED AC SOURCE FOR TWO CASES OF SERIES COMBINATION OF (i) INDUCTANCE L1, CAPACITANCE C1 AND RESISTANCE R1 AND (ii)INDUCTANCE L2 ,CAPACITANCE C2 AND RESISTANCE R2 WHERE R2>R1 . WRITE THE RELATION BETWEEN L1,C1 AND L2,C2 AT RESONANCE.

Answer 1

For case 2.

Since from the graph, it is clear that in first case the curve at resonance is sharper than that in case 2. So case 1 is better suited for tuning the receiver set.
