Question 113: AC fundamentals

Question

At very high frequencies, the effective impendence of the given circuit will be ________________ $$\Omega$$.

Accepted Answer

X
L
= 2$$\pi$$fL
f is very large
$$	herefore$$ X
L
is very large hence open circuit.
$${X_C} = {1 \over {2\pi fC}}$$
f is very large.
$$	herefore$$ X
C
is very small, hence short circuit.
Final circuit
$$ 	herefore $$ $${Z_{eq}} = 1 + {{2 	imes 2} \over {2 + 2}} = 2$$
