Question

Физика: Aseries resonant circuit has l= 1.01 henries, c=20µf and r=70 ohms to which an alternating e.m.f of 100 volts is applied. at which frequency of the applied voltage will the circuit be in resonance? ​

ivan445 · Answer

ответ:

пропускная способность=r÷l

снова,

полоса пропускания= резонансная частота (fr)÷ q-фактор.

q=(1/r) × (l/c)^1/2

=1÷100 ×(8/0.5)^1/2

=40

теперь, 100/8=fr / 40

=fr=(100×40)÷8=4000/8=500rad/s (ans.)
