  1. An inductance L having a resistance R is connected to an alternating source of angular frequency ω. The quality factor Q of the inductance is​​
    1. R
      ωL
    2. ωL
      		²
      R
    3. R
      		1/2
      ωL
    4. ωL
      R
Correct Option: D

Quality Factor =
Potential drop accross capacitor or inductor
Potential drop accross R

= IωL = ωL
IRR
