Lr Circuit Formula. For example current is still the same everywhere in this series circuit. Q factor for a series resonant circuit rl circuits solve.
V r is still in phase with i and v l is still 90 out of phase with i. Q factor is directly proportional to selectivity. In the first period of time τ the current rises from zero to 0 632 i0 since i i0 1 e 1 i0 1 0 368 0 632 i0.
τ l r τ l r where τ has units of seconds since 1 h 1 ω s.
For this circuit we will assign experimental values as follows. For example current is still the same everywhere in this series circuit. V r is still in phase with i and v l is still 90 out of phase with i. R 25ω l 1 h and v ac 10 v rms.
