Two magnetically uncoupled inductive coils have Q factors q1 and q2 at the chosen operating frequency. Their respective resistances are R1 and R2. When connected in series, their effective Q factor at the same operating frequency is
-
- q1R1 + q2R2
- q1/R1 + q2/R2
- (q1R1 + q2R2 )/(R1 + R2)
- q1R2 + q2R1
Correct Option: C
| q1 = | ⇒ L1 = | ; q2 = | |||
| R1 | W | R2 |
when connected in series
Leq = L1 + L2,
| qeq = | = | = | |||
| Req | R1 + R2 | R1 + R2 |
