Question 209: AC fundamentals

Question

An AC circuit has R= 100 $$\Omega $$, C = 2 $$\mu $$F and L = 80 mH, connected in series. The quality factor of the
circuit is :

Accepted Answer

$$Q = {1 \over R}\sqrt {{L \over C}} $$
= $${1 \over {100}}\sqrt {{{80 	imes {{10}^{ - 3}}} \over {2 	imes {{10}^{ - 6}}}}} $$
= $${1 \over {100}}\sqrt {40 	imes {{10}^3}} $$
= $${{200} \over {100}}$$ = 2
