Quality factor in a series RLC circuit is given by, $(Q = \frac{1}{R}\sqrt {\frac{L}{C}})$
If R, L and C double from its original value, the quality factor becomes half of the previous value.
New quality factor (Q) = 100/2 = 50
If R, L and C double from its original value, the quality factor becomes half of the previous value.
New quality factor (Q) = 100/2 = 50
