At very high frequencies, the effective impedance of the given circuit will be _________ $Ω .$

Question diagram: At very high frequencies, the effective impedance of the giv

Answer:

2.00

Solution:

For $ω \to \infty$
$\frac{1}{ω C} \to 0 \Rightarrow$ capacitance acts as short circuit
& $ω L \to \infty$ Inductance acts as open circuit

$Z = 1 + \frac{2 \times 2}{2 + 2} = 2 Ω$
