For very high frequencies, the effective impedance of the circuit (shown in the figure) will be

For very high frequencies, the effective impedance of the circuit (shown in the figure) will be

Options

A $1 \Omega$
B $3 \Omega$
C $4 \Omega$
D $6 \Omega$

Correct answer

B. $3 \Omega$

Step-by-step solution

X_L=\omega L

x_C=\frac{1}{\omega C}

at very high frequency

X_C=0, X_L=\infty

For very high frequencies, the effective impedance of the circuit (shown in the figure) will be

Z=(1+2) \Omega=3 \Omega
