At resonance, what is impedance of a series rlc circuit?
less than r
equal to r
larger than r
it depends on many other considerations, such as the values of l and c.
which of the following does the quality factor of the circuit depend on? (select all that apply.) ?
1) the width of the resonance
2) c
3) l
4) r

Impedance Z given as

At resonance

Z=R

At the resonance condition the impedance of a series RLC  will be equal to the R.

---------------------------------------------------------------------------------------------

The quality factor of the circuit depends on R ,L ,C and width of the resonance.

Quality factor Q

BW= Band width

f=Frequency at resonance

the answer would be c
