Question 227: AC fundamentals

Question

For an RLC circuit driven with voltage of amplitude vm and frequency $${\omega _0}$$ = $${1 \over {\sqrt {LC} }}$$ the current exhibits resonance. The quality factor, Q is given by :

Accepted Answer

Quality factor (Q) = $${{Angular\,\,{\mathop{m Re}
olimits} sonance} \over {Bandwith}}$$
= $${{{1 \over {\sqrt {LC} }}} \over {{R \over L}}}$$
= $${{{\omega _0}} \over {{R \over L}}}$$
= $${{{\omega _0}L} \over R}$$

Answer

$${{CR} \over {{\omega _0}}}$$

Answer

$${{{\omega _0}L} \over R}$$

Answer

$${{{\omega _0}R} \over L}$$

Answer

$${R \over {\left( {{\omega _0}C} \right)}}$$
