Circuit A is a series LCR circuit with C_ A =C and L_ A =L ....

Circuit A is a series LCR circuit with

C_{\mathrm{A}}=C

and

L_{\mathrm{A}}=L

. Another circuit B has

C_{\mathrm{B}}=2 C

and

L_{\mathrm{B}}=L / 2

. Both the circuits have the same resistance and the capacitor and the inductance are assumed to be ideal components. Each of the circuits is connected to the same sinusoidal voltage source. Therefore,

Options

Aboth the circuits have the same resonant frequency.
Bboth the circuits carry the same peak current.
Cresonance curve for circuit A is more sharp than that for circuit B .
Dresonance curve for circuit $B$ is more sharp than that for circuit $A$ .

Correct answer

C. resonance curve for circuit A is more sharp than that for circuit B .
