PHXII07:ALTERNATING CURRENT
356127
\(LC\) oscillations are similar and analogous to the mechanical oscillations of a block attached to a spring. The electrical equivalent of the force constant of the spring is
1 Reciprocal of capacitive reactance
2 Capacitive reactance
3 Reciprocal of capacitance
4 Capacitance
Explanation:
Equation describing \(LC\) circuit oscillation: \(L\frac{{{d^2}q}}{{d{t^2}}} + \frac{1}{C}q = 0\) Equation describing spring-mass system oscillation: \(m\frac{{{d^2}x}}{{d{t^2}}} + kx = 0\) Hence \(k\) is equivalent to \(1/C\).
