Physics Question on Alternating current
A circuit contains a capacitor and inductance each with negligible resistance. The capacitor is initially charged and the charging battery is disconnected. At subsequent time, the charge on the capacitor will
A
increase exponentially
B
decrease exponentially
C
decrease linearly
D
remain constant
Answer
remain constant
Explanation
Solution
When a charged capacitor is allowed to discharge through a resistance less inductor, electrical oscillations of constant amplitude are produced in the circuit. These are called L-C oscillations.
