:بارك الله فيكم اخوتي على جهودكم واتمنى ان تساعدوني في حل هذا السؤال قبل يوم الاحد اكون ممنونة لكم
اليكم السؤال
if aseries LRC circuit is connected across the terminals of an electric generator that produces avoltage
E(t=Ecoswt
the flow of electrical charge q throug the circuit is given by the following second order diff. eqn
Ld2q/dt2 +Rdq/dt +1/Cq =Ecoswt
verify the correspondingshown in the table between the parameter
of a driven mechanical oscillator and the above driven electrical oscillator
Table 1: Analogies Between the LRC Circuit and
the Damped Driven Oscillator.
LRC Circuit Oscillator
Inductor L Mass m
Resistor R Shock Absorber ¸
Capacitor C¡1 Spring k
Applied Voltage V0 Applied Force F0
Charge Q Position x
Current _Q = I Velocity x_ = v
calculate the Q of the electrical circuit in terms of L .R and C
show that the case of weak damping Q can be written as Q=R0/R
R0تساوي الجذر التربيعي لL/C
يارب الاقي الحل عندكم وتساعدوني بارك الله فيكم
